We do listen.* ## β‘ Performance This package offer better performance than its counterpart Chardet. Here are some numbers. | Package | Accuracy | Mean per file (ms) | File per sec (est) | | ------------- | :-------------: | :------------------: | :------------------: | | [chardet](https://github.com/chardet/chardet) | 92 % | 220 ms | 5 file/sec | | charset-normalizer | **98 %** | **40 ms** | 25 file/sec | | Package | 99th percentile | 95th percentile | 50th percentile | | ------------- | :-------------: | :------------------: | :------------------: | | [chardet](https://github.com/chardet/chardet) | 1115 ms | 300 ms | 27 ms | | charset-normalizer | 460 ms | 240 ms | 18 ms | Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload. > Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows. > And yes, these results might change at any time. The dataset can be updated to include more files. > The actual delays heavily depends on your CPU capabilities. The factors should remain the same. [cchardet](https://github.com/PyYoshi/cChardet) is a non-native (cpp binding) and unmaintained faster alternative with a better accuracy than chardet but lower than this package. If speed is the most important factor, you should try it. ## β¨ Installation Using PyPi for latest stable ```sh pip install charset-normalizer -U ``` If you want a more up-to-date `unicodedata` than the one available in your Python setup. ```sh pip install charset-normalizer[unicode_backport] -U ``` ## π Basic Usage ### CLI This package comes with a CLI. ``` usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD] file [file ...] The Real First Universal Charset Detector. 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 ``` :tada: 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())) ``` *Normalize any text file* ```python from charset_normalizer import normalize try: normalize('./my_subtitle.srt') # should write to disk my_subtitle-***.srt except IOError as e: print('Sadly, we are unable to perform charset normalization.', str(e)) ``` *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 chaos, 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 chaos/mess and coherence according to **YOU ?** *Chaos :* 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. I know that my interpretation of what is chaotic is very subjective, 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. ## 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© 2019 [Ahmed TAHRI @Ousret](https://github.com/Ousret).<br /> This project is [MIT](https://github.com/Ousret/charset_normalizer/blob/master/LICENSE) licensed.
