SYNOPSIS ^

  use strict;

  # 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
