Re^4: Can the "#" character be passed via $ENV{QUERY_STRING} ?

[mdillon]

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.

You are both correct. s/%(\d\d)/chr $1/eg will do fine if all you care about are encoded #'s (but then, you might as well use the faster and shorter s/%23/#/g). But if you want to be more general, use what mdillon states.
