IDNA — Internationalized Domain Names in Applications

idna implements the Internationalized Domain Names in Applications (IDNA 2008, RFC 5891) protocol and Unicode IDNA Compatibility Processing (UTS #46) for Python. It is the modern replacement for the built-in encodings.idna module, which only supports the obsolete IDNA 2003 standard. Current version is 3.11 (Python 3.8+); releases are irregular but active, with security patches and Unicode data updates driving most releases.
