The recently approved standard C++ include support for wide character
(wchar_t).
My problem is with fstream. I can't use wide character filenames when
opening a file with both fstream constructor and open method: it doesn't
appear to exist any open method accepting a wide character pointer as
filename.
Thus the following code doesn't work:

wchar_t *l_str;
...
std::fstream l_file;
l_file.open(l_str,std::ios::binary|std::ios::in);

How can I open a file with a wide character name using standard C++?
If in the C++ standard wide character names for file streams were
deliberately omitted how can I open correctly a file in order to have it
work also in the eastern countries (for example Japan)?
Is it always possible to translate a wide character string to a MBCS
(Multi - Byte Character String) and use the MBCS as filename in the open
method of fstream?

Thanks,
Dr. Simone Petruzzi
