NAME

URI::_punycode - encodes Unicode string in Punycode

SYNOPSIS

  use strict;
  use warnings;
  use utf8;

  use URI::_punycode qw(encode_punycode decode_punycode);

  # encode a unicode string
  my $punycode = encode_punycode('http://☃.net'); # http://.net-xc8g
  $punycode = encode_punycode('bücher'); # bcher-kva
  $punycode = encode_punycode('他们为什么不说中文'); # ihqwcrb4cv8a8dqg056pqjye

  # decode a punycode string back into a unicode string
  my $unicode = decode_punycode('http://.net-xc8g'); # http://☃.net
  $unicode = decode_punycode('bcher-kva'); # bücher
  $unicode = decode_punycode('ihqwcrb4cv8a8dqg056pqjye'); # 他们为什么不说中文

DESCRIPTION

URI::_punycode is a module to encode / decode Unicode strings into Punycode, an efficient encoding of Unicode for use with IDNA.
