I don't think we need to say anything special, the conversion to wchar_t
* is just as defined as that to char *. it is a locale dependent
operation just like withCString and friends. one would make their
decision as to which to use based on the library they are trying to bind
too, if a wchar_t interface is supported it should be prefered because
it is more likely to preserve character codes.
