## Version 6.2.0 (March 16, 2024)
|
||||
|
||||
- Fixed a case where an en-dash and a space near other mojibake would be
|
||||
interpreted (probably incorrectly) as MacRoman mojibake.
|
||||
- Added [project.urls] metadata to pyproject.toml.
|
||||
- README contains license clarifications for entitled jerks.
|
||||
|
||||
## Version 6.1.3 (November 21, 2023)
|
||||
|
||||
- Updated wcwidth.
|
||||
- Switched to the Apache 2.0 license.
|
||||
- Dropped support for Python 3.7.
|
||||
|
||||
## Version 6.1.2 (February 17, 2022)
|
||||
|
||||
- Added type information for `guess_bytes`.
|
||||
|
||||
## Version 6.1.1 (February 9, 2022)
|
||||
|
||||
- Updated the heuristic to fix the letter ß in UTF-8/MacRoman mojibake,
|
||||
which had regressed since version 5.6.
|
||||
|
||||
- Packaging fixes to pyproject.toml.
|
||||
|
||||
## Version 6.1 (February 9, 2022)
|
||||
|
||||
- Updated the heuristic to fix the letter Ñ with more confidence.
|
||||
|
||||
- Fixed type annotations and added py.typed.
|
||||
|
||||
- ftfy is packaged using Poetry now, and wheels are created and uploaded to
|
||||
PyPI.
|
||||
|
||||
## Version 6.0.3 (May 14, 2021)
|
||||
|
||||
- Allow the keyword argument `fix_entities` as a deprecated alias for
|
||||
`unescape_html`, raising a warning.
|
||||
|
||||
- `ftfy.formatting` functions now disregard ANSI terminal escapes when
|
||||
calculating text width.
|
||||
|
||||
|
||||
## Version 6.0.2 (May 4, 2021)
|
||||
|
||||
This version is purely a cosmetic change, updating the maintainer's e-mail
|
||||
address and the project's canonical location on GitHub.
|
||||
|
||||
|
||||
## Version 6.0.1 (April 12, 2021)
|
||||
|
||||
- The `remove_terminal_escapes` step was accidentally not being used. This
|
||||
version restores it.
|
||||
|
||||
- Specified in setup.py that ftfy 6 requires Python 3.6 or later.
|
||||
|
||||
- Use a lighter link color when the docs are viewed in dark mode.
|
||||
|
||||
## Version 6.0 (April 2, 2021)
|
||||
|
||||
- New function: `ftfy.fix_and_explain()` can describe all the transformations
|
||||
that happen when fixing a string. This is similar to what
|
||||
`ftfy.fixes.fix_encoding_and_explain()` did in previous versions, but it
|
||||
can fix more than the encoding.
|
||||
|
||||
- `fix_and_explain()` and `fix_encoding_and_explain()` are now in the top-level
|
||||
ftfy module.
|
||||
|
||||
- Changed the heuristic entirely. ftfy no longer needs to categorize every
|
||||
Unicode character, but only characters that are expected to appear in
|
||||
mojibake.
|
||||
|
||||
- Because of the new heuristic, ftfy will no longer have to release a new
|
||||
version for every new version of Unicode. It should also run faster and
|
||||
use less RAM when imported.
|
||||
|
||||
- The heuristic `ftfy.badness.is_bad(text)` can be used to determine whether
|
||||
there appears to be mojibake in a string. Some users were already using
|
||||
the old function `sequence_weirdness()` for that, but this one is actually
|
||||
designed for that purpose.
|
||||
|
||||
- Instead of a pile of named keyword arguments, ftfy functions now take in
|
||||
a TextFixerConfig object. The keyword arguments still work, and become
|
||||
settings that override the defaults in TextFixerConfig.
|
||||
|
||||
- Added support for UTF-8 mixups with Windows-1253 and Windows-1254.
|
||||
|
||||
- Overhauled the documentation: https://ftfy.readthedocs.org
|
||||
|
||||
## Version 5.9 (February 10, 2021)
|
||||
|
||||
This version is brought to you by the letter à and the number 0xC3.
|
||||
|
||||
- Tweaked the heuristic to decode, for example, "Ã " as the letter "à"
|
||||
more often.
|
||||
|
||||
- This combines with the non-breaking-space fixer to decode "Ã " as "à" as
|
||||
well. However, in many cases, the text " Ã " was intended to be " à ",
|
||||
preserving the space -- the underlying mojibake had two spaces after it, but
|
||||
the Web coalesced them into one. We detect this case based on common French
|
||||
and Portuguese words, and preserve the space when it appears intended.
|
||||
|
||||
Thanks to @zehavoc for bringing to my attention how common this case is.
|
||||
|
||||
- Updated the data file of Unicode character categories to Unicode 13, as
|
||||
used in Python 3.9. (No matter what version of Python you're on, ftfy uses
|
||||
the same data.)
|
||||
|
||||
## Version 5.8 (July 17, 2020)
|
||||
|
||||
- Improved detection of UTF-8 mojibake of Greek, Cyrillic, Hebrew, and Arabic
|
||||
scripts.
|
||||
|
||||
- Fixed the undeclared dependency on setuptools by removing the use of
|
||||
`pkg_resources`.
|
||||
|
||||
## Version 5.7 (February 18, 2020)
|
||||
|
||||
- Updated the data file of Unicode character categories to Unicode 12.1, as
|
||||
used in Python 3.8. (No matter what version of Python you're on, ftfy uses
|
||||
the same data.)
|
||||
|
||||
- Corrected an omission where short sequences involving the ACUTE ACCENT
|
||||
character were not being fixed.
|
||||
|
||||
## Version 5.6 (August 7, 2019)
|
||||
|
||||
- The `unescape_html` function now supports all the HTML5 entities that appear
|
||||
in `html.entities.html5`, including those with long names such as
|
||||
`˝`.
|
||||
|
||||
- Unescaping of numeric HTML entities now uses the standard library's
|
||||
`html.unescape`, making edge cases consistent.
|
||||
|
||||
(The reason we don't run `html.unescape` on all text is that it's not always
|
||||
appropriate to apply, and can lead to false positive fixes. The text
|
||||
"This&NotThat" should not have "&Not" replaced by a symbol, as
|
||||
`html.unescape` would do.)
|
||||
|
||||
- On top of Python's support for HTML5 entities, ftfy will also convert HTML
|
||||
escapes of common Latin capital letters that are (nonstandardly) written
|
||||
in all caps, such as `Ñ` for `Ñ`.
|
||||
|
||||
|
||||
## Version 5.5.1 (September 14, 2018)
|
||||
|
||||
- Added Python 3.7 support.
|
||||
|
||||
- Updated the data file of Unicode character categories to Unicode 11, as used
|
||||
in Python 3.7.0. (No matter what version of Python you're on, ftfy uses the
|
||||
same data.)
|
||||
|
||||
|
||||
## Version 5.5 (September 6, 2018)
|
||||
|
||||
- Recent versions have emphasized making a reasonable attempt to fix short,
|
||||
common mojibake sequences, such as `û`. In this version, we've expanded the
|
||||
heuristics to recognize these sequences in MacRoman as well as Windows-125x
|
||||
encodings.
|
||||
|
||||
- A related rule for fixing isolated Windows-1252/UTF-8 mixups, even when they
|
||||
were inconsistent with the rest of the string, claimed to work on Latin-1/UTF-8
|
||||
mixups as well, but in practice it didn't. We've made the rule more robust.
|
||||
|
||||
- Fixed a failure when testing the CLI on Windows.
|
||||
|
||||
- Removed the `pytest-runner` invocation from setup.py, as it created complex
|
||||
dependencies that would stop setup.py from working in some environments.
|
||||
The `pytest` command still works fine. `pytest-runner` is just too clever.
|
||||
|
||||
|
||||
## Version 5.4.1 (June 14, 2018)
|
||||
|
||||
- Fixed a bug in the `setup.py` metadata.
|
||||
|
||||
This bug was causing ftfy, a package that fixes encoding mismatches, to not
|
||||
install in some environments due to an encoding mismatch. (We were really
|
||||
putting the "meta" in "metadata" here.)
|
||||
|
||||
|
||||
## Version 5.4 (June 1, 2018)
|
||||
|
||||
- ftfy was still too conservative about fixing short mojibake sequences,
|
||||
such as "août" -> "août", when the broken version contained punctuation
|
||||
such as curly or angle quotation marks.
|
||||
|
||||
The new heuristic observes in some cases that, even if quotation marks are
|
||||
expected to appear next to letters, it is strange to have an accented capital
|
||||
A before the quotation mark and more letters after the quotation mark.
|
||||
|
||||
- Provides better metadata for the new PyPI.
|
||||
|
||||
- Switched from nosetests to pytest.
|
||||
|
||||
|
||||
## Version 5.3 (January 25, 2018)
|
||||
|
||||
- A heuristic has been too conservative since version 4.2, causing a regression
|
||||
compared to previous versions: ftfy would fail to fix mojibake of common
|
||||
characters such as `á` when seen in isolation. A new heuristic now makes it
|
||||
possible to fix more of these common cases with less evidence.
|
||||
|
||||
|
||||
## Version 5.2 (November 27, 2017)
|
||||
|
||||
- The command-line tool will not accept the same filename as its input
|
||||
and output. (Previously, this would write a zero-length file.)
|
||||
|
||||
- The `uncurl_quotes` fixer, which replaces curly quotes with straight quotes,
|
||||
now also replaces MODIFIER LETTER APOSTROPHE.
|
||||
|
||||
- Codepoints that contain two Latin characters crammed together for legacy
|
||||
encoding reasons are replaced by those two separate characters, even in NFC
|
||||
mode. We formerly did this just with ligatures such as `fi` and `IJ`, but now
|
||||
this includes the Afrikaans digraph `ʼn` and Serbian/Croatian digraphs such as
|
||||
`dž`.
|
||||
|
||||
|
||||
## Version 5.1.1 and 4.4.3 (May 15, 2017)
|
||||
|
||||
These releases fix two unrelated problems with the tests, one in each version.
|
||||
|
||||
- v5.1.1: fixed the CLI tests (which are new in v5) so that they pass
|
||||
on Windows, as long as the Python output encoding is UTF-8.
|
||||
|
||||
- v4.4.3: added the `# coding: utf-8` declaration to two files that were
|
||||
missing it, so that tests can run on Python 2.
|
||||
|
||||
## Version 5.1 (April 7, 2017)
|
||||
|
||||
- Removed the dependency on `html5lib` by dropping support for Python 3.2.
|
||||
|
||||
We previously used the dictionary `html5lib.constants.entities` to decode
|
||||
HTML entities. In Python 3.3 and later, that exact dictionary is now in the
|
||||
standard library as `html.entities.html5`.
|
||||
|
||||
- Moved many test cases about how particular text should be fixed into
|
||||
`test_cases.json`, which may ease porting to other languages.
|
||||
|
||||
The functionality of this version remains the same as 5.0.2 and 4.4.2.
|
||||
|
||||
|
||||
## Version 5.0.2 and 4.4.2 (March 21, 2017)
|
||||
|
||||
Added a `MANIFEST.in` that puts files such as the license file and this
|
||||
changelog inside the source distribution.
|
||||
|
||||
|
||||
## Version 5.0.1 and 4.4.1 (March 10, 2017)
|
||||
|
||||
Bug fix:
|
||||
|
||||
- The `unescape_html` fixer will decode entities between `€` and `Ÿ`
|
||||
as what they would be in Windows-1252, even without the help of
|
||||
`fix_encoding`.
|
||||
|
||||
This better matches what Web browsers do, and fixes a regression that version
|
||||
4.4 introduced in an example that uses `…` as an ellipsis.
|
||||
|
||||
|
||||
## Version 5.0 (February 17, 2017)
|
||||
|
||||
Breaking changes:
|
||||
|
||||
- Dropped support for Python 2. If you need Python 2 support, you should get
|
||||
version 4.4, which has the same features as this version.
|
||||
|
||||
- The top-level functions require their arguments to be given as keyword
|
||||
arguments.
|
||||
|
||||
Version 5.0 also now has tests for the command-line invocation of ftfy.
|
||||
|
||||
|
||||
## Version 4.4.0 (February 17, 2017)
|
||||
|
||||
Heuristic changes:
|
||||
|
||||
- ftfy can now fix mojibake involving the Windows-1250 or ISO-8859-2 encodings.
|
||||
|
||||
- The `fix_entities` fixer is now applied after `fix_encoding`. This makes
|
||||
more situations resolvable when both fixes are needed.
|
||||
|
||||
- With a few exceptions for commonly-used characters such as `^`, it is now
|
||||
considered "weird" whenever a diacritic appears in non-combining form,
|
||||
such as the diaeresis character `¨`.
|
||||
|
||||
- It is also now weird when IPA phonetic letters, besides `ə`, appear next to
|
||||
capital letters.
|
||||
|
||||
- These changes to the heuristics, and others we've made in recent versions,
|
||||
let us lower the "cost" for fixing mojibake in some encodings, causing them
|
||||
to be fixed in more cases.
|
||||
|
||||
|
||||
## Version 4.3.1 (January 12, 2017)
|
||||
|
||||
Bug fix:
|
||||
|
||||
- `remove_control_chars` was removing U+0D ('\r') prematurely. That's the
|
||||
job of `fix_line_breaks`.
|
||||
|
||||
|
||||
## Version 4.3.0 (December 29, 2016)
|
||||
|
||||
ftfy has gotten by for four years without dependencies on other Python
|
||||
libraries, but now we can spare ourselves some code and some maintenance burden
|
||||
by delegating certain tasks to other libraries that already solve them well.
|
||||
This version now depends on the `html5lib` and `wcwidth` libraries.
|
||||
|
||||
Feature changes:
|
||||
|
||||
- The `remove_control_chars` fixer will now remove some non-ASCII control
|
||||
characters as well, such as deprecated Arabic control characters and
|
||||
byte-order marks. Bidirectional controls are still left as is.
|
||||
|
||||
This should have no impact on well-formed text, while cleaning up many
|
||||
characters that the Unicode Consortium deems "not suitable for markup"
|
||||
(see Unicode Technical Report #20).
|
||||
|
||||
- The `unescape_html` fixer uses a more thorough list of HTML entities,
|
||||
which it imports from `html5lib`.
|
||||
|
||||
- `ftfy.formatting` now uses `wcwidth` to compute the width that a string
|
||||
will occupy in a text console.
|
||||
|
||||
Heuristic changes:
|
||||
|
||||
- Updated the data file of Unicode character categories to Unicode 9, as used
|
||||
in Python 3.6.0. (No matter what version of Python you're on, ftfy uses the
|
||||
same data.)
|
||||
|
||||
Pending deprecations:
|
||||
|
||||
- The `remove_bom` option will become deprecated in 5.0, because it has been
|
||||
superseded by `remove_control_chars`.
|
||||
|
||||
- ftfy 5.0 will remove the previously deprecated name `fix_text_encoding`. It
|
||||
was renamed to `fix_encoding` in 4.0.
|
||||
|
||||
- ftfy 5.0 will require Python 3.2 or later, as planned. Python 2 users, please
|
||||
specify `ftfy < 5` in your dependencies if you haven't already.
|
||||
|
||||
|
||||
## Version 4.2.0 (September 28, 2016)
|
||||
|
||||
Heuristic changes:
|
||||
|
||||
- Math symbols next to currency symbols are no longer considered 'weird' by the
|
||||
heuristic. This fixes a false positive where text that involved the
|
||||
multiplication sign and British pounds or euros (as in '5×£35') could turn
|
||||
into Hebrew letters.
|
||||
|
||||
- A heuristic that used to be a bonus for certain punctuation now also gives a
|
||||
bonus to successfully decoding other common codepoints, such as the
|
||||
non-breaking space, the degree sign, and the byte order mark.
|
||||
|
||||
- In version 4.0, we tried to "future-proof" the categorization of emoji (as a
|
||||
kind of symbol) to include codepoints that would likely be assigned to emoji
|
||||
later. The future happened, and there are even more emoji than we expected.
|
||||
We have expanded the range to include those emoji, too.
|
||||
|
||||
ftfy is still mostly based on information from Unicode 8 (as Python 3.5 is),
|
||||
but this expanded range should include the emoji from Unicode 9 and 10.
|
||||
|
||||
- Emoji are increasingly being modified by variation selectors and skin-tone
|
||||
modifiers. Those codepoints are now grouped with 'symbols' in ftfy, so they
|
||||
fit right in with emoji, instead of being considered 'marks' as their Unicode
|
||||
category would suggest.
|
||||
|
||||
This enables fixing mojibake that involves iOS's new diverse emoji.
|
||||
|
||||
- An old heuristic that wasn't necessary anymore considered Latin text with
|
||||
high-numbered codepoints to be 'weird', but this is normal in languages such
|
||||
as Vietnamese and Azerbaijani. This does not seem to have caused any false
|
||||
positives, but it caused ftfy to be too reluctant to fix some cases of broken
|
||||
text in those languages.
|
||||
|
||||
The heuristic has been changed, and all languages that use Latin letters
|
||||
should be on even footing now.
|
||||
|
||||
|
||||
## Version 4.1.1 (April 13, 2016)
|
||||
|
||||
- Bug fix: in the command-line interface, the `-e` option had no effect on
|
||||
Python 3 when using standard input. Now, it correctly lets you specify
|
||||
a different encoding for standard input.
|
||||
|
||||
|
||||
## Version 4.1.0 (February 25, 2016)
|
||||
|
||||
Heuristic changes:
|
||||
|
||||
- ftfy can now deal with "lossy" mojibake. If your text has been run through
|
||||
a strict Windows-1252 decoder, such as the one in Python, it may contain
|
||||
the replacement character <20> (U+FFFD) where there were bytes that are
|
||||
unassigned in Windows-1252.
|
||||
|
||||
Although ftfy won't recover the lost information, it can now detect this
|
||||
situation, replace the entire lossy character with <20>, and decode the rest of
|
||||
the characters. Previous versions would be unable to fix any string that
|
||||
contained U+FFFD.
|
||||
|
||||
As an example, text in curly quotes that gets corrupted `“ like this â€<C3A2>`
|
||||
now gets fixed to be `“ like this <20>`.
|
||||
|
||||
- Updated the data file of Unicode character categories to Unicode 8.0, as used
|
||||
in Python 3.5.0. (No matter what version of Python you're on, ftfy uses the
|
||||
same data.)
|
||||
|
||||
- Heuristics now count characters such as `~` and `^` as punctuation instead
|
||||
of wacky math symbols, improving the detection of mojibake in some edge cases.
|
||||
|
||||
New features:
|
||||
|
||||
- A new module, `ftfy.formatting`, can be used to justify Unicode text in a
|
||||
monospaced terminal. It takes into account that each character can take up
|
||||
anywhere from 0 to 2 character cells.
|
||||
|
||||
- Internally, the `utf-8-variants` codec was simplified and optimized.
|
||||
|
||||
|
||||
## Version 4.0.0 (April 10, 2015)
|
||||
|
||||
Breaking changes:
|
||||
|
||||
- The default normalization form is now NFC, not NFKC. NFKC replaces a large
|
||||
number of characters with 'equivalent' characters, and some of these
|
||||
replacements are useful, but some are not desirable to do by default.
|
||||
|
||||
- The `fix_text` function has some new options that perform more targeted
|
||||
operations that are part of NFKC normalization, such as
|
||||
`fix_character_width`, without requiring hitting all your text with the huge
|
||||
mallet that is NFKC.
|
||||
|
||||
- If you were already using NFC normalization, or in general if you want to
|
||||
preserve the *spacing* of CJK text, you should be sure to set
|
||||
`fix_character_width=False`.
|
||||
|
||||
- The `remove_unsafe_private_use` parameter has been removed entirely, after
|
||||
two versions of deprecation. The function name `fix_bad_encoding` is also
|
||||
gone.
|
||||
|
||||
New features:
|
||||
|
||||
- Fixers for strange new forms of mojibake, including particularly clear cases
|
||||
of mixed UTF-8 and Windows-1252.
|
||||
|
||||
- New heuristics, so that ftfy can fix more stuff, while maintaining
|
||||
approximately zero false positives.
|
||||
|
||||
- The command-line tool trusts you to know what encoding your *input* is in,
|
||||
and assumes UTF-8 by default. You can still tell it to guess with the `-g`
|
||||
option.
|
||||
|
||||
- The command-line tool can be configured with options, and can be used as a
|
||||
pipe.
|
||||
|
||||
- Recognizes characters that are new in Unicode 7.0, as well as emoji from
|
||||
Unicode 8.0+ that may already be in use on iOS.
|
||||
|
||||
Deprecations:
|
||||
|
||||
- `fix_text_encoding` is being renamed again, for conciseness and consistency.
|
||||
It's now simply called `fix_encoding`. The name `fix_text_encoding` is
|
||||
available but emits a warning.
|
||||
|
||||
Pending deprecations:
|
||||
|
||||
- Python 2.6 support is largely coincidental.
|
||||
|
||||
- Python 2.7 support is on notice. If you use Python 2, be sure to pin a
|
||||
version of ftfy less than 5.0 in your requirements.
|
||||
|
||||
|
||||
## Version 3.4.0 (January 15, 2015)
|
||||
|
||||
New features:
|
||||
|
||||
- `ftfy.fixes.fix_surrogates` will fix all 16-bit surrogate codepoints,
|
||||
which would otherwise break various encoding and output functions.
|
||||
|
||||
Deprecations:
|
||||
|
||||
- `remove_unsafe_private_use` emits a warning, and will disappear in the
|
||||
next minor or major version.
|
||||
|
||||
|
||||
## Version 3.3.1 (December 12, 2014)
|
||||
|
||||
This version restores compatibility with Python 2.6.
|
||||
|
||||
|
||||
## Version 3.3.0 (August 16, 2014)
|
||||
|
||||
Heuristic changes:
|
||||
|
||||
- Certain symbols are marked as "ending punctuation" that may naturally occur
|
||||
after letters. When they follow an accented capital letter and look like
|
||||
mojibake, they will not be "fixed" without further evidence.
|
||||
An example is that "MARQUÉ…" will become "MARQUÉ...", and not "MARQUɅ".
|
||||
|
||||
New features:
|
||||
|
||||
- `ftfy.explain_unicode` is a diagnostic function that shows you what's going
|
||||
on in a Unicode string. It shows you a table with each code point in
|
||||
hexadecimal, its glyph, its name, and its Unicode category.
|
||||
|
||||
- `ftfy.fixes.decode_escapes` adds a feature missing from the standard library:
|
||||
it lets you decode a Unicode string with backslashed escape sequences in it
|
||||
(such as "\u2014") the same way that Python itself would.
|
||||
|
||||
- `ftfy.streamtester` is a release of the code that I use to test ftfy on
|
||||
an endless stream of real-world data from Twitter. With the new heuristics,
|
||||
the false positive rate of ftfy is about 1 per 6 million tweets. (See
|
||||
the "Accuracy" section of the documentation.)
|
||||
|
||||
Deprecations:
|
||||
|
||||
- Python 2.6 is no longer supported.
|
||||
|
||||
- `remove_unsafe_private_use` is no longer needed in any current version of
|
||||
Python. This fixer will disappear in a later version of ftfy.
|
||||
|
||||
|
||||
## Version 3.2.0 (June 27, 2014)
|
||||
|
||||
- `fix_line_breaks` fixes three additional characters that are considered line
|
||||
breaks in some environments, such as Javascript, and Python's "codecs"
|
||||
library. These are all now replaced with \n:
|
||||
|
||||
U+0085 <control>, with alias "NEXT LINE"
|
||||
U+2028 LINE SEPARATOR
|
||||
U+2029 PARAGRAPH SEPARATOR
|
||||
|
||||
|
||||
## Version 3.1.3 (May 15, 2014)
|
||||
|
||||
- Fix `utf-8-variants` so it never outputs surrogate codepoints, even on
|
||||
Python 2 where that would otherwise be possible.
|
||||
|
||||
|
||||
## Version 3.1.2 (January 29, 2014)
|
||||
|
||||
- Fix bug in 3.1.1 where strings with backslashes in them could never be fixed
|
||||
|
||||
|
||||
## Version 3.1.1 (January 29, 2014)
|
||||
|
||||
- Add the `ftfy.bad_codecs` package, which registers new codecs that can
|
||||
decoding things that Python may otherwise refuse to decode:
|
||||
|
||||
- `utf-8-variants`, which decodes CESU-8 and its Java lookalike
|
||||
|
||||
- `sloppy-windows-*`, which decodes character-map encodings while treating
|
||||
unmapped characters as Latin-1
|
||||
|
||||
- Simplify the code using `ftfy.bad_codecs`.
|
||||
|
||||
|
||||
## Version 3.0.6 (November 5, 2013)
|
||||
|
||||
- `fix_entities` can now be True, False, or 'auto'. The new case is True, which
|
||||
will decode all entities, even in text that already contains angle brackets.
|
||||
This may also be faster, because it doesn't have to check.
|
||||
- `build_data.py` will refuse to run on Python < 3.3, to prevent building
|
||||
an inconsistent data file.
|
||||
|
||||
|
||||
## Version 3.0.5 (November 1, 2013)
|
||||
|
||||
- Fix the arguments to `fix_file`, because they were totally wrong.
|
||||
|
||||
|
||||
## Version 3.0.4 (October 1, 2013)
|
||||
|
||||
- Restore compatibility with Python 2.6.
|
||||
|
||||
|
||||
## Version 3.0.3 (September 9, 2013)
|
||||
|
||||
- Fixed an ugly regular expression bug that prevented ftfy from importing on a
|
||||
narrow build of Python.
|
||||
|
||||
|
||||
## Version 3.0.2 (September 4, 2013)
|
||||
|
||||
- Fixed some false positives.
|
||||
|
||||
- Basically, 3.0.1 was too eager to treat text as MacRoman or cp437 when
|
||||
three consecutive characters coincidentally decoded as UTF-8. Increased the
|
||||
cost of those encodings so that they have to successfully decode multiple
|
||||
UTF-8 characters.
|
||||
|
||||
- See `tests/test_real_tweets.py` for the new test cases that were added as a
|
||||
result.
|
||||
|
||||
|
||||
## Version 3.0.1 (August 30, 2013)
|
||||
|
||||
- Fix bug in `fix_java_encoding` that led to only the first instance of
|
||||
CESU-8 badness per line being fixed
|
||||
- Add a fixer that removes unassigned characters that can break Python 3.3
|
||||
(http://bugs.python.org/issue18183)
|
||||
|
||||
|
||||
## Version 3.0 (August 26, 2013)
|
||||
|
||||
- Generally runs faster
|
||||
- Idempotent
|
||||
- Simplified decoding logic
|
||||
- Understands more encodings and more kinds of mistakes
|
||||
- Takes options that enable or disable particular normalization steps
|
||||
- Long line handling: now the time-consuming step (`fix_text_encoding`) will be
|
||||
consistently skipped on long lines, but all other fixes will apply
|
||||
- Tested on millions of examples from Twitter, ensuring a near-zero rate of
|
||||
false positives
|
||||
|
||||
|
||||
## Version 2.0.2 (June 20, 2013)
|
||||
|
||||
- Fix breaking up of long lines, so it can't go into an infinite loop
|
||||
|
||||
|
||||
## Version 2.0.1 (March 19, 2013)
|
||||
|
||||
- Restored Python 2.6 support
|
||||
|
||||
|
||||
## Version 2.0 (January 30, 2013)
|
||||
|
||||
- Python 3 support
|
||||
- Use fast Python built-ins to speed up fixes
|
||||
- Bugfixes
|
||||
|
||||
|
||||
## Version 1.0 (August 24, 2012)
|
||||
|
||||
- Made into its own package with no dependencies, instead of a part of
|
||||
`metanl`

|

|
||||
## What it does
|
||||
|
||||
Here are some examples (found in the real world) of what ftfy can do:
|
||||
|
||||
ftfy can fix mojibake (encoding mix-ups), by detecting patterns of characters that were clearly meant to be UTF-8 but were decoded as something else:
|
||||
|
||||
>>> import ftfy
|
||||
>>> ftfy.fix_text('✔ No problems')
|
||||
'✔ No problems'
|
||||
|
||||
Does this sound impossible? It's really not. UTF-8 is a well-designed encoding that makes it obvious when it's being misused, and a string of mojibake usually contains all the information we need to recover the original string.
|
||||
|
||||
ftfy can fix multiple layers of mojibake simultaneously:
|
||||
|
||||
>>> ftfy.fix_text('The Mona Lisa doesn’t have eyebrows.')
|
||||
"The Mona Lisa doesn't have eyebrows."
|
||||
|
||||
It can fix mojibake that has had "curly quotes" applied on top of it, which cannot be consistently decoded until the quotes are uncurled:
|
||||
|
||||
>>> ftfy.fix_text("l’humanité")
|
||||
"l'humanité"
|
||||
|
||||
ftfy can fix mojibake that would have included the character U+A0 (non-breaking space), but the U+A0 was turned into an ASCII space and then combined with another following space:
|
||||
|
||||
>>> ftfy.fix_text('Ã\xa0 perturber la réflexion')
|
||||
'à perturber la réflexion'
|
||||
>>> ftfy.fix_text('à perturber la réflexion')
|
||||
'à perturber la réflexion'
|
||||
|
||||
ftfy can also decode HTML entities that appear outside of HTML, even in cases where the entity has been incorrectly capitalized:
|
||||
|
||||
>>> # by the HTML 5 standard, only 'PÉREZ' is acceptable
|
||||
>>> ftfy.fix_text('P&EACUTE;REZ')
|
||||
'PÉREZ'
|
||||
|
||||
These fixes are not applied in all cases, because ftfy has a strongly-held goal of avoiding false positives -- it should never change correctly-decoded text to something else.
|
||||
|
||||
The following text could be encoded in Windows-1252 and decoded in UTF-8, and it would decode as 'MARQUɅ'. However, the original text is already sensible, so it is unchanged.
|
||||
|
||||
>>> ftfy.fix_text('IL Y MARQUÉ…')
|
||||
'IL Y MARQUÉ…'
|
||||
|
||||
## Installing
|
||||
|
||||
ftfy is a Python 3 package that can be installed using `pip`:
|
||||
|
||||
pip install ftfy
|
||||
|
||||
(Or use `pip3 install ftfy` on systems where Python 2 and 3 are both globally
|
||||
installed and `pip` refers to Python 2.)
|
||||
|
||||
### Local development
|
||||
|
||||
ftfy is developed using `poetry`. Its `setup.py` is vestigial and is not the
|
||||
recommended way to install it.
|
||||
|
||||
[Install Poetry](https://python-poetry.org/docs/master/#installing-with-the-official-installer), check out this repository, and run `poetry install` to install ftfy for local development, such as experimenting with the heuristic or running tests.
|
||||
|
||||
## Who maintains ftfy?
|
||||
|
||||
I'm Robyn Speer, also known as Elia Robyn Lake. You can find me
|
||||
[on GitHub](https://github.com/rspeer) or [Cohost](https://cohost.org/arborelia).
|
||||
|
||||
## Citing ftfy
|
||||
|
||||
ftfy has been used as a crucial data processing step in major NLP research.
|
||||
|
||||
It's important to give credit appropriately to everyone whose work you build on
|
||||
in research. This includes software, not just high-status contributions such as
|
||||
mathematical models. All I ask when you use ftfy for research is that you cite
|
||||
it.
|
||||
|
||||
ftfy has a citable record [on Zenodo](https://zenodo.org/record/2591652).
|
||||
A citation of ftfy may look like this:
|
||||
|
||||
Robyn Speer. (2019). ftfy (Version 5.5). Zenodo.
|
||||
http://doi.org/10.5281/zenodo.2591652
|
||||
|
||||
In BibTeX format, the citation is::
|
||||
|
||||
@misc{speer-2019-ftfy,
|
||||
author = {Robyn Speer},
|
||||
title = {ftfy},
|
||||
note = {Version 5.5},
|
||||
year = 2019,
|
||||
howpublished = {Zenodo},
|
||||
doi = {10.5281/zenodo.2591652},
|
||||
url = {https://doi.org/10.5281/zenodo.2591652}
|
||||
}
|
||||
|
||||
## Important license clarifications
|
||||
|
||||
If you do not follow ftfy's license, you do not have a license to ftfy.
|
||||
|
||||
This sounds obvious and tautological, but there are people who think open source licenses mean that they can just do what they want, especially in the field of generative AI. It's a permissive license but you still have to follow it. The [Apache license](https://www.apache.org/licenses/LICENSE-2.0) is the only thing that gives you permission to use and copy ftfy; otherwise, all rights are reserved.
|
||||
|
||||
If you use or distribute ftfy, you must follow the terms of the [Apache license](https://www.apache.org/licenses/LICENSE-2.0), including that you must attribute the author of ftfy (Robyn Speer) correctly.
|
||||
|
||||
You _may not_ make a derived work of ftfy that obscures its authorship, such as by putting its code in an AI training dataset, including the code in AI training at runtime, or using a generative AI that copies code from such a dataset.
|
||||
|
||||
At my discretion, I may notify you of a license violation, and give you a chance to either remedy it or delete all copies of ftfy in your possession.
