NAME
       IDNA::Punycode - encodes Unicode string in Punycode
SYNOPSIS
         use IDNA::Punycode;
         idn_prefix('xn--');
         $punycode = encode_punycode($unicode);
         $unicode  = decode_punycode($punycode);
DESCRIPTION
       IDNA::Punycode is a module to encode / decode Unicode strings into
       Punycode, an efficient encoding of Unicode for use with IDNA.
       This module requires Perl 5.6.0 or over to handle UTF8 flagged Unicode
       strings.
FUNCTIONS
       This module exports following functions by default.
       encode_punycode
             $punycode = encode_punycode($unicode);
           takes Unicode string (UTF8-flagged variable) and returns Punycode
           encoding for it.
       decode_punycode
             $unicode = decode_punycode($punycode)
           takes Punycode encoding and returns original Unicode string.
       idn_prefix
             idn_prefix($prefix);
           causes encode_punycode() to add $prefix to ACE-string after
           conversion.  As a side-effect decode_punycode() will only consider
           strings beginning with $prefix as punycode representations.
           According to RFC 3490 the ACE prefix "xn--" had been chosen as the
           standard.  Thus, "xn--" is also the default ACE prefix.  For
           compatibility I'm leaving idn_prefix() in the module.  Use
           "idn_prefix(undef)" to get the old behaviour.
       These functions throws exceptionsn on failure. You can catch 'em via
       "eval".
