Unicode Data Browser 1.4 (Default branch)
04-17-2008
UnicodeDataBrowser is a browser for the UnicodeData.txt file, which contains much useful information but is not easily read by humans. It creates a scrollable table in which columns represent properties. The table may be sorted on any column. Abbreviations are expanded and characters cross-referenced in decomposition and casing fields are named. Regular expression search restricted to a selected column is available. The set of characters for which information is displayed may be restricted to those characters matching a regular expression on a specified property.License: GNU General Public License v3Changes:|

IDNA::Punycode(3pm) User Contributed Perl Documentation IDNA::Punycode(3pm) 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 compat- ibility 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". AUTHORS
