Encode::Punycode - Encode plugin for Punycode (RFC 3492)
use Encode; $unicode = decode('Punycode', $punycode); $punycode = encode('Punycode', $unicode);
Encode::Punycode is an Encode plugin, which implements the Punycode encoding.
Punycode is an instance of a more general algorithm called Bootstring, which allows strings composed from a small set of "basic" code points to uniquely represent any string of code points drawn from a larger set. Punycode is Bootstring with particular parameter values appropriate for IDNA. For a more generic (but less efficient) Bootstring implementation, see Encode::Bootstring.
This module does not do any string preparation or mappings as specified by Nameprep. It does not do add any prefix or suffix, either. For higher-level handling of full Internationalised Domain Names, see Net::IDN::Encode.
