Never ever "remove invalid characters". Always "remove everything except the safe characters". What if someone sends you a newline? Or a character with code 0? Or ... Your regexp makes very little sense. You definitely should go read perlretut or something. The [] denotes a character class, there is no difference whatsoever between [<sup>] and [<>ups]!
