opening filename containing Unicode characters in VC6 compiler

We have a maintainance project that was build on VC6 compilers. At some part of the code we have a file open function using ifstream.open() method which fails when the filename contains UNICODE characters like chinese characters. Since VC6 compiler doesn't support the wchar_t* version of open function, is there a way i can open this type of file? i tried FILE* _wfopen method too but it fails too.

Thanks in advance

As per RemyLebeau's guidance - i tried using errno,i got the value as 22 which indicates invalid parameter. Plese see my code std::wstring filename=_wgetenv(L"IVT_FILENAME"); FILE * stream; stream=_wfopen(filename.c_str(),L"r");

This works perfectly fine in vc9 and file opens and im able to read contents. Don't know why it doesnt work in vc6. The value of stream is NULL

The actual problem was with _wgetenv function. It doesnot work properly in VC6 compiler. Replacing it with GetEnvironmentVariable solves the issue and file is opened
