NAME

SYNOPSIS

  use Encode; use Encode::Punycode;
  
  $unicode  = decode('Punycode', $punycode);
  $punycode = encode('Punycode', $unicode);

DESCRIPTION

This module provides an "Encode" interface for the Punycode encoding, which is defined in RFC 3492. This is not very useful because Punycode is a special-purpose encoding that is limited to fairly short strings. Please consider using Net::IDN::Punycode directly, or even Net::IDN::Encode.

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.

PLEASE NOTE: 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.
