You probably do not want to exclude ;, &, = and +.

Although they're don't have to be encoded, according to the rfc, ; and & separate key/value pairs in a query string, = separates key and value in a key/value pair in a query string, and + often is a space (chr(32)) in query strings. Because query strings are a very common reason for using URI encoding, I think it's unwise to not encode these characters.

The characters I mentioned are part of the "reserved" characters, and since version 1.16, URI::Escape does encode them (not encoding them cause a LOT of trouble in many situations).
