IDNA::Punycode - DEPRECATED module for IDNA and Punyode
This module is deprecated.
Please use Net::IDN::Encode to handle full domain names and Net::IDN::Punycode for raw Punycode encoding.
This module is provided for compatibility with earlier versions of IDNA::Punycode.
IDNA::Punycode
The following functions are imported by default. If you also use Net::IDN::Punycode, be sure to disable import from this module:
use Net::IDN::Punycode
use IDNA::Punycode();
Sets $IDNA::Punycode::PREFIX to $prefix.
$IDNA::Punycode::PREFIX
$prefix
Do not use this function in larger applications or environments in which multiple application share global variables (such as mod_perl). Instead, set the variable locally:
local $IDNA::Punycode::PREFIX = 'yo--';
If $IDNA::Punycode::PREFIX is '', encodes $input with Punycode.
''
$input
If $IDNA::Punycode::PREFIX is not '', encodes $input with Punycode and adds the prefix if $input does contain non-base characters (i. e. characters above U+007F). If $input does not contain any non-base characters, it is returned as-is.
This function does not do any string preparation as specified by nameprep or other stringprep profiles. Use Net::IDN::Encode if you just want to convert a domain name.
This function will croak on invalid input.
If $IDNA::Punycode::PREFIX is '', decodes $input with Punycode.
If $IDNA::Punycode::PREFIX is not '', checks whether $input starts with the prefix. If $input starts with the prefix, the prefix is removed and the remainder is decoded with Punycode. If $input does not start with the prefix, it is returned as-is.
Of course, this function does not do any string preparation as specified by nameprep or other stringprep profiles (or some sort of de-preparation).
