I can't judge rigthfuly, if this is a feasible approach.

 From my experience, I use to work with wchar_t on windows in gui
applications, while linux based console program ususaly use only char
(non-unicode) encoding.

So it seems, that both char and wchar_t usage is equaly important. Your approach
would penalize "char" approach in the means of additional conversions and memory

Maybe it does not matter too much, but you should take this argument into consideration.
