Wise Monks,
I have a question regarding special character conversions. At the moment I convert a url string in the following way: 

$url_string =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

[download]
How would I convert the other way around? I need to convert characters such as '&',':',etc to their '%' hex equivalents?
Thanks in advance for any help
