It would be nice for people -- if any ;-) -- who need unicode 
to have a flag to widen char itself rather than have a separate 
type. A separate type is unusable for programs where unicode 
is pervasive as you don't want to write to 2 versions of every 
function that takes a string (unless I'm mistaken and some
magic already allows a function that takes a string to also 
accept a wide string).

If there's only WideChar available, it's only useful if you have 
the odd opaque field which is unicode and most of your program 
isn't. It's of some use, but someone who needs unicode 
everywhere will not use such a language, as there are quite a
few languages with usable support.
