Discover originating encoding used on text file. Normalize text to unicode. positional arguments: files File(s) to be analysed optional arguments: -h, --help show this help message and exit -v, --verbose Display complementary information about file if any. Stdout will contain logs about the detection process. -a, --with-alternative Output complementary possibilities if any. Top-level JSON WILL be a list. -n, --normalize Permit to normalize input file. If not set, program does not write anything. -m, --minimal Only output the charset detected to STDOUT. Disabling JSON output. -r, --replace Replace file when trying to normalize it instead of creating a new one. -f, --force Replace file without asking if you are sure, use this flag with caution. -t THRESHOLD, --threshold THRESHOLD Define a custom maximum amount of chaos allowed in decoded content. 0. <= chaos <= 1. --version Show version information and exit. ``` ```bash normalizer ./data/sample.1.fr.srt ``` or ```bash python -m charset_normalizer ./data/sample.1.fr.srt ``` π Since version 1.4.0 the CLI produce easily usable stdout result in JSON format. ```json { "path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt", "encoding": "cp1252", "encoding_aliases": [ "1252", "windows_1252" ], "alternative_encodings": [ "cp1254", "cp1256", "cp1258", "iso8859_14", "iso8859_15", "iso8859_16", "iso8859_3", "iso8859_9", "latin_1", "mbcs" ], "language": "French", "alphabets": [ "Basic Latin", "Latin-1 Supplement" ], "has_sig_or_bom": false, "chaos": 0.149, "coherence": 97.152, "unicode_path": null, "is_preferred": true } ``` ### Python *Just print out normalized text* ```python from charset_normalizer import from_path results = from_path('./my_subtitle.srt') print(str(results.best())) ``` *Upgrade your code without effort* ```python from charset_normalizer import detect ``` The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible. See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/) ## π Why When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a reliable alternative using a completely different method. Also! I never back down on a good challenge! I **don't care** about the **originating charset** encoding, because **two different tables** can produce **two identical rendered string.** What I want is to get readable text, the best I can. In a way, **I'm brute forcing text decoding.** How cool is that ? π Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode. ## π° How - Discard all charset encoding table that could not fit the binary content. - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding. - Extract matches with the lowest mess detected. - Additionally, we measure coherence / probe for a language. **Wait a minute**, what is noise/mess and coherence according to **YOU ?** *Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then **I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text). I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to improve or rewrite it. *Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design. ## β‘ Known limitations - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters)) - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content. ## β οΈ About Python EOLs **If you are running:** - Python >=2.7,<3.5: Unsupported - Python 3.5: charset-normalizer < 2.1 - Python 3.6: charset-normalizer < 3.1 - Python 3.7: charset-normalizer < 4.0 Upgrade your Python interpreter as soon as possible. ## π€ Contributing Contributions, issues and feature requests are very much welcome.<br /> Feel free to check [issues page](https://github.com/ousret/charset_normalizer/issues) if you want to contribute. ## π License Copyright Β© [Ahmed TAHRI @Ousret](https://github.com/Ousret).<br /> This project is [MIT](https://github.com/Ousret/charset_normalizer/blob/master/LICENSE) licensed.

Add syntax sugar \_\_bool\_\_ for results CharsetMatches list-container (PR #91) ### Removed - The project no longer raise warning on tiny content given for detection, will be simply logged as warning instead (PR #92) ### Fixed - In some rare case, the chunks extractor could cut in the middle of a multi-byte character and could mislead the mess detection (PR #95) - Some rare 'space' characters could trip up the UnprintablePlugin/Mess detection (PR #96) - The MANIFEST.in was not exhaustive (PR #78) ## [2.0.4](https://github.com/Ousret/charset_normalizer/compare/2.0.3...2.0.4) (2021-07-30) ### Fixed - The CLI no longer raise an unexpected exception when no encoding has been found (PR #70) - Fix accessing the 'alphabets' property when the payload contains surrogate characters (PR #68) - The logger could mislead (explain=True) on detected languages and the impact of one MBCS match (PR #72) - Submatch factoring could be wrong in rare edge cases (PR #72) - Multiple files given to the CLI were ignored when publishing results to STDOUT. (After the first path) (PR #72) - Fix line endings from CRLF to LF for certain project files (PR #67) ### Changed - Adjust the MD to lower the sensitivity, thus improving the global detection reliability (PR #69 #76) - Allow fallback on specified encoding if any (PR #71) ## [2.0.3](https://github.com/Ousret/charset_normalizer/compare/2.0.2...2.0.3) (2021-07-16) ### Changed - Part of the detection mechanism has been improved to be less sensitive, resulting in more accurate detection results. Especially ASCII. (PR #63) - According to the community wishes, the detection will fall back on ASCII or UTF-8 in a last-resort case. (PR #64) ## [2.0.2](https://github.com/Ousret/charset_normalizer/compare/2.0.1...2.0.2) (2021-07-15) ### Fixed - Empty/Too small JSON payload miss-detection fixed. Report from [@tseaver](https://github.com/tseaver) (PR #59) ### Changed - Don't inject unicodedata2 into sys.modules from [@akx](https://github.com/akx) (PR #57) ## [2.0.1](https://github.com/Ousret/charset_normalizer/compare/2.0.0...2.0.1) (2021-07-13) ### Fixed - Make it work where there isn't a filesystem available, dropping assets frequencies.json. Report from [@sethmlarson](https://github.com/sethmlarson). (PR #55) - Using explain=False permanently disable the verbose output in the current runtime (PR #47) - One log entry (language target preemptive) was not show in logs when using explain=True (PR #47) - Fix undesired exception (ValueError) on getitem of instance CharsetMatches (PR #52) ### Changed - Public function normalize default args values were not aligned with from_bytes (PR #53) ### Added - You may now use charset aliases in cp_isolation and cp_exclusion arguments (PR #47) ## [2.0.0](https://github.com/Ousret/charset_normalizer/compare/1.4.1...2.0.0) (2021-07-02) ### Changed - 4x to 5 times faster than the previous 1.4.0 release. At least 2x faster than Chardet. - Accent has been made on UTF-8 detection, should perform rather instantaneous. - The backward compatibility with Chardet has been greatly improved. The legacy detect function returns an identical charset name whenever possible. - The detection mechanism has been slightly improved, now Turkish content is detected correctly (most of the time) - The program has been rewritten to ease the readability and maintainability. (+Using static typing)+ - utf_7 detection has been reinstated. ### Removed - This package no longer require anything when used with Python 3.5 (Dropped cached_property) - Removed support for these languages: Catalan, Esperanto, Kazakh, Baque, VolapΓΌk, Azeri, Galician, Nynorsk, Macedonian, and Serbocroatian. - The exception hook on UnicodeDecodeError has been removed. ### Deprecated - Methods coherence_non_latin, w_counter, chaos_secondary_pass of the class CharsetMatch are now deprecated and scheduled for removal in v3.0 ### Fixed - The CLI output used the relative path of the file(s). Should be absolute. ## [1.4.1](https://github.com/Ousret/charset_normalizer/compare/1.4.0...1.4.1) (2021-05-28) ### Fixed - Logger configuration/usage no longer conflict with others (PR #44) ## [1.4.0](https://github.com/Ousret/charset_normalizer/compare/1.3.9...1.4.0) (2021-05-21) ### Removed - Using standard logging instead of using the package loguru. - Dropping nose test framework in favor of the maintained pytest. - Choose to not use dragonmapper package to help with gibberish Chinese/CJK text. - Require cached_property only for Python 3.5 due to constraint. Dropping for every other interpreter version. - Stop support for UTF-7 that does not contain a SIG. - Dropping PrettyTable, replaced with pure JSON output in CLI. ### Fixed - BOM marker in a CharsetNormalizerMatch instance could be False in rare cases even if obviously present. Due to the sub-match factoring process. - Not searching properly for the BOM when trying utf32/16 parent codec. ### Changed - Improving the package final size by compressing frequencies.json. - Huge improvement over the larges payload. ### Added - CLI now produces JSON consumable output. - Return ASCII if given sequences fit. Given reasonable confidence. ## [1.3.9](https://github.com/Ousret/charset_normalizer/compare/1.3.8...1.3.9) (2021-05-13) ### Fixed - In some very rare cases, you may end up getting encode/decode errors due to a bad bytes payload (PR #40) ## [1.3.8](https://github.com/Ousret/charset_normalizer/compare/1.3.7...1.3.8) (2021-05-12) ### Fixed - Empty given payload for detection may cause an exception if trying to access the `alphabets` property. (PR #39) ## [1.3.7](https://github.com/Ousret/charset_normalizer/compare/1.3.6...1.3.7) (2021-05-12) ### Fixed - The legacy detect function should return UTF-8-SIG if sig is present in the payload.
