Command Blocks do not test for unicode based scoreboards

Basically I have an idea of vanilla permissions using unchangeable scoreboards and happen to walk onto this bug. basically create a scoreboard objective using unicode format in the actual scoreboard. then try to test for it in the brackets after the @<selector> and it wont read the scoreboard but if you do it with a normal scoreboard it works perfectly fine.

tip: use /give in a server console to give you a command block with the unicode symbol or use mcedit to edit in the symbol on existing command blocks in the world.
