## プロジェクトの歴史と使われ方

chardet is Python's long-running universal character encoding detector, exposed as both a library and the `chardetect` command-line tool.

### プロジェクトの歴史

The official README says Mark Pilgrim originally created chardet in 2006 as a Python port of Mozilla's universal charset detection library. After Pilgrim disappeared from the web in 2011, maintenance continued under later Python maintainers.

### 採用の歴史

chardet became a standard dependency in Python text-processing stacks because it solved the practical problem of guessing encodings for unknown byte streams. The supplied package facts show Homebrew packaging plus Debian and Ubuntu documentation packages, while the README documents normal installation with `pip install chardet`.

### 使われ方

Users call `chardet.detect`, `detect_all`, or `UniversalDetector` from Python, or run `chardetect` on files or stdin to print a guessed encoding and confidence.

### パッケージ好きにとっての重要性

chardet is package-nerd significant because it sits at the messy boundary between package metadata, HTTP downloads, archives, and text decoding. It is also notable for a 2026 chardet 7 rewrite that kept the package name and public API while changing implementation and license.

### タイムライン

- 2006: Mark Pilgrim created chardet as a Python port of Mozilla's universal charset detector.
- 2008: chardet 1.0.1 released on PyPI according to the official README history.
- 2011: Project maintenance continued after Pilgrim deleted his online accounts.
- 2012: chardet/chardet public GitHub repository created.
- 2017: chardet 3.0.x releases published on GitHub.
- 2026: chardet 7.0 released as a ground-up 0BSD-licensed rewrite under the same package name.

### Related projects

- Mozilla's universal charset detection library is the upstream idea chardet originally ported.
- charset-normalizer is a related Python encoding detector compared directly in the chardet 7 README.
