We should definitely do that. The functions aren't implementing UTF-16.

Note that Windows *does* now implement UTF16 I think, but EFI still
claims to be UCS2 only. 

If I interpret this correctly, the claim is basically that Windows was
"always" actually UTF16, but just never used any of the code points
where you'd be able to notice the difference:
