Optimizing a CFStringRef for CFStringCompare usage

Suppose I have a bunch (many hundreds) of CFStringRefs that could have come from anywhere and which are cached and I need to sort them (possibly multiple times) as quickly as possible using CFStringCompare. Is there anything I could do to my cached versions so that the guts of CFStringCompare runs as fast as possible.

I am thinking maybe ensuring that my cached versions have real unicode storage and are not left as 8-bit ascii for some strings etc.

Is this worthwhile and if so what is the correct way of getting my strings in such a state.
