NAME ^

Encode::Punycode - Encode plugin for Punycode (RFC 3492)

SYNOPSIS ^

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

DESCRIPTION ^

Encode::Punycode is an Encode plugin, which implements the Punycode encoding.

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.
