+> A library that helps you read text from an unknown charset encoding.<br /> Motivated by `chardet`,
+> I'm trying to resolve the issue by taking a new approach.
+> All IANA character set names for which the Python core library provides codecs are supported.
+> You can also register your own set of codecs, and yes, it would work as-is.
+
+This project offers you an alternative to **Universal Charset Encoding Detector**, also known as **Chardet**.

+[^1]: They are clearly using specific code for a specific encoding even if covering most of used one.
+[^2]: Chardet 7.0+ was relicensed from LGPL-2.1 to MIT following an AI-assisted rewrite. This relicensing is disputed on two independent grounds: **(a)** the original author [contests](https://github.com/chardet/chardet/issues/327) that the maintainer had the right to relicense, arguing the rewrite is a derivative work of the LGPL-licensed codebase since it was not a clean room implementation; **(b)** the copyright claim itself is [questionable](https://github.com/chardet/chardet/issues/334) given the code was primarily generated by an LLM, and AI-generated output may not be copyrightable under most jurisdictions. Either issue alone could undermine the MIT license. Beyond licensing, the rewrite raises questions about responsible use of AI in open source: key architectural ideas pioneered by charset-normalizer - notably decode-first validity filtering (our foundational approach since v1) and encoding pairwise similarity with the same algorithm and threshold — surfaced in chardet 7 without acknowledgment. The project also imported test files from charset-normalizer to train and benchmark against it, then claimed superior accuracy on those very files. Charset-normalizer has always been MIT-licensed, encoding-agnostic by design, and built on a verifiable human-authored history.

+
+~Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.~ No longer the case since Chardet 7.0+
+
+> 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.
+> Chardet claims on his documentation to have a greater accuracy than us based on the dataset they trained Chardet on(...)
+> Well, it's normal, the opposite would have been worrying. Whereas charset-normalizer don't train on anything, our solution
+> is based on a completely different algorithm, still heuristic through, it does not need weights across every encoding tables.
+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 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
+```
+
+🎉 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",

+    ],
+    "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/)
+
+## 😇 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 ? 😎
+
+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.
+
+## 🍰 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.
+
+## ⚡ 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.
+
+## ⚠️ 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
+
+Upgrade your Python interpreter as soon as possible.

+
+Support for [Internationalized Domain Names in Applications
+(IDNA)](https://tools.ietf.org/html/rfc5891) and [Unicode IDNA
+Compatibility Processing](https://unicode.org/reports/tr46/). It
+supersedes the standard library's `encodings.idna`, which only
+implements the 2003 specification, offering broader script coverage and
+limiting domains with known security vulnerabilities.
+
+## Usage
+
+Package may be installed from [PyPI](https://pypi.org/project/idna/) via
+the typical methods (e.g. `python3 -m pip install idna`)
+
+For typical usage, the `encode` and `decode` functions will take a
+domain name argument and perform a conversion to ASCII-compatible encoding
+(known as A-labels), or to Unicode strings (known as U-labels)
+respectively.
+
+```pycon
+>>> import idna
+>>> idna.encode('ドメイン.テスト')
+b'xn--eckwd4c7c.xn--zckzah'
+>>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
+ドメイン.テスト
+```
+
+Conversions can be applied at a per-label basis using the `ulabel` or
+`alabel` functions for specialized use cases.
+
+
+### Compatibility Mapping (UTS #46)
+
+This library provides support for [Unicode IDNA Compatibility
+Processing](https://unicode.org/reports/tr46/) which normalizes input from
+different potential ways a user may input a domain prior to performing the IDNA
+conversion operations. This functionality, known as a
+[mapping](https://tools.ietf.org/html/rfc5895), is considered by the
+specification to be a local user-interface issue distinct from IDNA
+conversion functionality.
+
+For example, "Königsgäßchen" is not a permissible label as capital letters
+are not allowed. UTS 46 will convert this into lower case prior to applying
+the IDNA conversion.
+
+```pycon
+>>> import idna
+>>> idna.encode('Königsgäßchen')
+...
+idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed
+>>> idna.encode('Königsgäßchen', uts46=True)
+b'xn--knigsgchen-b4a3dun'
+>>> idna.decode('xn--knigsgchen-b4a3dun')
+'königsgäßchen'
+```
+
+When performing a decode operation for display purposes, `decode()`
+accepts a `display=True` argument that leaves any `xn--` label that
+fails to decode unchanged. This is useful for user interface display
+where a domain is in use, the A-label form can be presented when it
+is not a valid IDN.
+
+
+## Exceptions
+
+All errors raised during conversion derive from the `idna.IDNAError`
+base class. The more specific exceptions are:
+
+* `idna.IDNABidiError` — raised when a label contains an illegal
+  combination of left-to-right and right-to-left characters.
+* `idna.InvalidCodepoint` — raised when a label contains a codepoint
+  that is INVALID for IDNA.
+* `idna.InvalidCodepointContext` — raised when a CONTEXTO or CONTEXTJ
+  codepoint appears in a position whose contextual requirements are
+  not satisfied.
+
+
+## Command-line tool
+
+The package supports command-line usage to convert domain names
+between their Unicode and ASCII-compatible forms. It can be run either
+as a module (`python3 -m idna`) or, once installed (such as with `uv
+tool` or `pipx`), via the `idna` script:
+
+```bash
+$ uv tool install idna
+$ idna xn--e1afmkfd.xn--p1ai
+пример.рф
+$ idna пример.рф
+xn--e1afmkfd.xn--p1ai
+```
+
+Mode can be specified with `-e`/`--encode` or `-d`/`--decode`, otherwise
+it will be chosen automatically based on the first input. Multiple
+domains can be supplied either as arguments or through standard input.
+UTS #46 mapping is applied by default, which lets the tool accept
+inputs that aren't strictly valid IDNA 2008 by normalising them first,
+pass `--strict` to disable UTS #46.
+
+Conversion failures are reported on stderr together with the
+offending input; processing continues with the remaining domains and
+the tool exits with a non-zero status if any conversion failed.
+
+
+## Additional Notes
+
+* **Version support**. This library supports Python 3.9 and higher.
+  As this library serves as a low-level toolkit for a variety of
+  applications, we strive to support all versions of Python that are
+  not beyond end-of-life.
+
+* **Emoji**. It is an occasional request to support emoji domains in
+  this library. Encoding of symbols like emoji is expressly prohibited by
+  the IDNA technical standard, and emoji domains are broadly phased
+  out across the domain industry due to associated security risks.
+
+* **Regenerating lookup tables**. The IDNA and UTS 46 functionality
+  relies upon pre-calculated lookup tables, generated using the
+  `idna-data` script in [`tools/`](tools/README.md).

+"""A PEP 517 interface to setuptools
+
+Previously, when a user or a command line tool (let's call it a "frontend")
+needed to make a request of setuptools to take a certain action, for
+example, generating a list of installation requirements, the frontend
+would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.
+
+PEP 517 defines a different method of interfacing with setuptools. Rather
+than calling "setup.py" directly, the frontend should:
+
+  1. Set the current directory to the directory with a setup.py file
+  2. Import this module into a safe python interpreter (one in which
+     setuptools can potentially set global variables or crash hard).
+  3. Call one of the functions defined in PEP 517.
+
+What each function does is defined in PEP 517. However, here is a "casual"
+definition of the functions (this definition should not be relied on for
+bug reports or API stability):
+
+  - `build_wheel`: build a wheel in the folder and return the basename
+  - `get_requires_for_build_wheel`: get the `setup_requires` to build
+  - `prepare_metadata_for_build_wheel`: get the `install_requires`
+  - `build_sdist`: build an sdist in the folder and return the basename
+  - `get_requires_for_build_sdist`: get the `setup_requires` to build
+
+Again, this is not a formal definition! Just a "taste" of the module.

+
+    This is an enhanced version of 'distutils.dist.Distribution' that
+    effectively adds the following new optional keyword arguments to 'setup()':
+
+     'install_requires' -- a string or sequence of strings specifying project
+        versions that the distribution requires when installed, in the format
+        used by 'pkg_resources.require()'.  They will be installed
+        automatically when the package is installed.  If you wish to use
+        packages that are not available in PyPI, or want to give your users an
+        alternate download location, you can add a 'find_links' option to the
+        '[easy_install]' section of your project's 'setup.cfg' file, and then
+        setuptools will scan the listed web pages for links that satisfy the
+        requirements.
+
+     'extras_require' -- a dictionary mapping names of optional "extras" to the
+        additional requirement(s) that using those extras incurs. For example,
+        this::
+
+            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+        indicates that the distribution can optionally provide an extra
+        capability called "reST", but it can only be used if docutils and
+        reSTedit are installed.  If the user installs your package using
+        EasyInstall and requests one of your extras, the corresponding
+        additional requirements will be installed if needed.
+
+     'package_data' -- a dictionary mapping package names to lists of filenames
+        or globs to use to find data files contained in the named packages.
+        If the dictionary has filenames or globs listed under '""' (the empty
+        string), those names will be searched for in every package, in addition
+        to any names for the specific package.  Data files found using these
+        names/globs will be installed along with the package, in the same
+        location as the package.  Note that globs are allowed to reference
+        the contents of non-package subdirectories, as long as you use '/' as
+        a path separator.  (Globs are automatically converted to
+        platform-specific paths at runtime.)
+
+    In addition to these new keywords, this class also has several new methods
+    for manipulating the distribution's contents.  For example, the 'include()'
+    and 'exclude()' methods can be thought of as in-place add and subtract
+    commands that add or remove packages, modules, extensions, and so on from
+    the distribution.
