Your suggestion only works for simple characters like ASCII. NSStrings store unicode and if your character is several unichars long then you could end up with gibberish. Use

- (NSRange)rangeOfComposedCharacterSequenceAtIndex:(NSUInteger)index;

if you want to determine how many unichars your character is. I use this to step through my strings to determine where the character borders occur.

Being fully unicode able is a bit of work but depends on what languages you use. I see a lot of asian text so most characters spill over from one space and so it's work that I need to do.
