[MacPerl] URL encoding

["John Springer" <john@digitalmx.com>]

I'm trying to do URL encoding in a script, just like the browser does
when it sends a query.
I'm using :
        $newchar='%'.hex(unpack("C",$char));
to encode (which is not correct).
I tried just hex($char) but that isn't right either.

I use:
        s/%(\w\w)/chr(hex($1))/
to decode (which I think is correct)

What is the correct encoding statement?  Also, do you know where I can
find a list of what characters need to be encoded, besides & and %?
