in thread Can the "#" character be passed via $ENV{QUERY_STRING} ?

You don't need to load all of CGI to do this if you are taking the whole QUERY_STRING as a single value. You can use URI:Escape directly. It is an extremely lightweight module. You'll want to use uri_unescape, like so: 
    use URI::Escape qw(uri_unescape);
    my $query_string = uri_unescape $ENV{QUERY_STRING};

    Just to note, uri_unescape is functionally:  s/%(\d\d)/chr $1/eg; if you don't even want to load the module.

      I think that should be: 
      s/%([0-9A-Fa-f]{2})/chr(hex($1))/eg

      In fact, that's pretty much exactly what's in URI::Escape, except that the module also handles scalar v. list context and multiple arguments. Using uri_unescape still seems preferable to me, since the resource overhead of using the module is basically nil and the mnemonic benefit of seeing uri_unescape instead of a regex is considerable.

        You know, you're completely correct, and that mostly proves your point about using a module. I theoretially knew what the proper code should be, but I wasn't paying attention and wrote something that was broken and didn't even think about it, the module would have been much easier.
