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.
