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 <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('bücher'); # bcher−kva
$punycode = encode_punycode('他 们 为 什 么 不 说 中 文 ') # 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'); # bücher
$unicode = decode_punycode('ihqwcrb4cv8a8dqg056pqjye'); # 他 们 为 什 么 不 说 中 文

Takes a Punycode encoding and returns original Unicode string.
