IDNA::Punycode(3) DEPRECATED module for IDNA and Punyode

DESCRIPTION

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".

FUNCTIONS

The following functions are imported by default. If you also "use Net::IDN::Punycode", be sure to disable import from this module: 

  use IDNA::Punycode();
idn_prefix($prefix)
Sets $IDNA::Punycode::PREFIX to $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 $IDNA::Punycode::PREFIX = 'yo--';
encode_punycode($input)
If $IDNA::Punycode::PREFIX is '', encodes $input with Punycode.

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.

decode_punycode($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).

This function will croak on invalid input.
