Can't you convert to UTF-16 during load? Then you don't need to 
translate at all.
I'm under the impression that you are keeping an UTF-8 data blob in an 
environment that mostly talks UTF-16; in that case, the cleanest 
solution would be to have the data blob in UTF-16, too. Of course I 
don't know how much of your code base you'd have to touch to change 
that, this could be quite nasty or surprisingly easy.
