There is simple no need for wchar_t on Linux. If you use a classical
encoding in your filesystem it is a 8bit one (except you use a Asian
language such as Japanese). All modern distributions switched already
to UTF-8 as default encoding and for this you don't need wchar_t as
well. Use ordinary char* streams for this ...

Remember that you know for UTF-8 always where the current character
stops if you just have a pointer to an arbritary byte (in the middle of
a multi-byte character). It's also useless to group bytes pairwise as a
valid UTF-8 character can consist of more than two bytes. char* is
really sufficent.
