%description
High-performance Unicode and Punycode processing for internationalized
domain names. The 'puny_encode()' / 'puny_decode()' helpers are a
low-level, RFC 3492 compliant Punycode codec for domain labels (the 'xn--'
ASCII-Compatible Encoding of RFC 5890/5891); they perform the raw
transform plus letter-digit-hyphen checks and do not apply Unicode IDNA
normalization. 'host_normalize()' is the Unicode Technical Standard #46
host-normalization entry point, mapping a host name to a canonical
lowercase ASCII comparison form (non-transitional profile, pinned default
Unicode version, selectable per call from the set the build ships). Aimed
at host normalization and data analysis workflows. Used as the Punycode
and IDNA engine by the 'pslr' and 'rurl' packages.
