There is a list of valid characters accepted for a passcode. That list was created, the characters debated, and a consensus reached by Apple engineers (I hope, for all our sakes. I don't want to imagine a world where this bare minimum level of engineering diligence wasn't done by a trillion dollar company)
Just have an automated keyboard test for every new release to ensure those characters aren't broken.
Agreed, but just to be clear; I was asking how would you test that assuming you still wanted to remove a character that was previously present.
