## 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) | 86 % | 200 ms | 5 file/sec | | |
| charset-normalizer | **98 %** | **10 ms** | 100 file/sec | | |
| Package | 99th percentile | 95th percentile | 50th percentile | | |
|-----------------------------------------------|:---------------:|:---------------:|:---------------:| | |
| [chardet](https://github.com/chardet/chardet) | 1200 ms | 287 ms | 23 ms | | |
| charset-normalizer | 100 ms | 50 ms | 5 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. | |
> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability | |
> (eg. Supported Encoding) Challenge-them if you want. | |
## β¨ Installation | |
Using pip: | |
```sh | |
pip install charset-normalizer -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 | |
``` | |
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. | |
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. | |

## [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) | |

- 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 | |

## [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. | |
