Note: carob is heavily using "wchar_t" and "std::wstring". wchar_t
does NOT need to be a unicode even if this is the most common case.
+It may even be locale-dependent.

Carob is supposed to be 100% portable to NON-unicode wchar_t systems
-(typically japanese), as long as it can find an appropriate
-wchar_t/UTF-8 codec to communicate with the controller.
