If it's just a one-liner to do that on Windows that seems like a 
reasonable solution.  (With a comment in the docs about what that one 
line is.)  Alternatively there could be something like:

#if WINDOWS
class FileName
{
public:
    FileName(const char *name);
    FileName(const wchar_t *name);
    ...
};
#else
typedef const char * FileName
#endif

But I think the latter option would be overkill if it's really simple to 
do the conversion on Windows.
