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.
This is more of a design choices discussion. As for Boost, it has wpath in its interfaces on Linux so the support is claimed. We made a design choices to use wchar_t cross-platform since the code is Windows/Linux. This is why I want to get it working. -- Alexei Alexandrov
