The one in NSString.m is used whenever anyone implements their own 
subclass of NSString.

The ones in GSString.m are used for the private concrete subclasses 
dealing with unicode strings, unicode mutable strings, byte encoded 
strings and byte encoded mutable strings.
Since the byte encoded strings cannot possible contain multibyte 
sequences, the implementation for that always returns the single 
character at the specified index.
