Question

Is there any Perl XS module with high-speed subroutines suitable for encoding/decoding of the non-standard %uXXXX unicode characters found in unicode cookies (especially Firefox)?

decoding: input = …%uXXXX… , output = a normal utf8 Perl string
encoding: input = a normal utf8 Perl string, output = …%uXXXX…

Now I’m decoding these strings using this code:

    $string =~ s/%u([A-Fa-f0-9]{4})/chr(hex($1))/eg;

but it would be nice to have a C-implemented version of it.

Answer 1

How about two?

• URI::Escape::XS
• CGI::Deurl::XS

URL::Encode::XS also exists, but does not meet the requirement.
