Open Sarcasm fighting copyrighted punctuation

pinkushun writes: SarcMark is a copyrighted punctuation mark, that claims "It's time that sarcasm is treated equally!", pretty damn cheeky while they're charging for their software, which only inserts their punctuation through a hotkey. Open Sarcasm is destroying SarcMark by advocating a new punctuation mark (not displaying here properly — alt+U0161) as the new open and free sarcasm symbol.
Either way, this will be one interesting turnout. With bad unicode support across the web, displaying the characters properly might be an issue. PS Left out sarcastic end sentence as /. doesn't display the U0161 character.
