This is probably not sufficient. The string @"é" can be represented
by two characters, an 'e' and a combining accent. It is unlikely to
be correct to insert a space between them. This is unrelated to lower
level issues, like some unicode code points taking more than one 16
bit unichar to represent.
The method -[NSString rangeOfComposedCharacterSequenceAtIndex:] will
give you chunks of characters that should not be broken up by
operations such as adding a space. You could use that.
The suggestion of modifying the kerning sounds better to me, though,
if it applies.
