How about:
NSCharacterSet *set = [NSCharacterSet
characterSetWithCharactersInString:theString];
BOOL characterIsInString = [set characterIsMember:someUnichar];
I guess you would have to loop through the unichar's in your set.
Or maybe [theString rangeOfCharacterFromSet:aSet] would be helpful.
Just some guesses.
