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('bucher'); # bcher-kva
         $punycode = encode_punycode(''); # ihqwcrb4cv8a8dqg056pqjye

         # decode a punycode string back into a unicode string
         my $unicode = decode_punycode('http://.net-xc8g'); # http://.net
         $unicode = decode_punycode('bcher-kva'); # bucher
         $unicode = decode_punycode('ihqwcrb4cv8a8dqg056pqjye'); #

DESCRIPTION
       URI::_punycode is a module to encode / decode Unicode strings into Punycode
       <https://tools.ietf.org/html/rfc3492>, an efficient encoding of Unicode for use with IDNA
       <https://tools.ietf.org/html/rfc5890>.

FUNCTIONS
       All functions throw exceptions on failure. You can "catch" them with Syntax::Keyword::Try
       or Try::Tiny. The following functions are exported by default.

   encode_punycode
         my $punycode = encode_punycode('http://.net');  # http://.net-xc8g
         $punycode = encode_punycode('bucher'); # bcher-kva
         $punycode = encode_punycode('') # ihqwcrb4cv8a8dqg056pqjye

       Takes a Unicode string (UTF8-flagged variable) and returns a Punycode encoding for it.

   decode_punycode
         my $unicode = decode_punycode('http://.net-xc8g'); # http://.net
         $unicode = decode_punycode('bcher-kva'); # bucher
         $unicode = decode_punycode('ihqwcrb4cv8a8dqg056pqjye'); #

       Takes a Punycode encoding and returns original Unicode string.
