NAME

Net::IDN::Punycode - A Bootstring encoding of Unicode for IDNA (RFC 3492)

SYNOPSIS

  use Net::IDN::Punycode;
  $punycode = encode_punycode($unicode);
  $unicode  = decode_punycode($punycode);

DESCRIPTION

This module 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.

Note that this module does not do any string preparation as specified by nameprep/stringprep. It does not do add any prefix or suffix, either.
