I don't think so. A string copy operation for a wide string needs to move 
twice as much data as a string copy operation for an ansistring. However, 
when walking through it, (take the widestring version of pos for example) 
the amount of work per character does not change.

The big trouble is the conversion stuff when you need communication with 
the outside world.
