It wraps POSIX wcwidth/wcswidth functions (or Markus Kuhn's implementation on non-POSIX systems) and provides the same API as the pure-Python wcwidth package, but with significantly faster execution through Cython compilation.\n\nThe library is useful when you need accurate terminal rendering calculations\u2014for instance, when aligning text in CLI tools, formatting table output, or handling mixed-width characters (like CJK ideographs that occupy two columns). It has no runtime dependencies and supports modern Python versions (3.11+) across major platforms with prebuilt wheels.","worth_installing":"Yes, if you need fast Unicode display-width calculations for terminal output. The library is actively maintained, has no security vulnerabilities, carries a permissive license, and offers substantial performance gains over pure-Python alternatives. Install friction is moderate but manageable with prebuilt wheels for all major platforms. Requires Python 3.11+."},"id":"cwcwidth","links":{"html":"https://skillfed.io/packages/cwcwidth","md":"https://skillfed.io/packages/cwcwidth.md","pypi":"https://pypi.org/project/cwcwidth/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-11-01","license_spdx":null,"license_treatment":"permissive","name":"cwcwidth","python_support":"supports_current","summary":"Python bindings for wc(s)width"},"popularity":{"monthly_downloads":575923,"position":5933,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.12"}
