I need to open a file as std::fstream (or actually any other std::ostream) when file name is "Unicode" file name. Under MSVC I have non-standard extension std::fstream::open(wchar_t const *,...) ? What can I do with other compilers like GCC (most important) and probably Borland compiler. I know that CRTL provides _wfopen but it gives C FILE * interface instead of io-streams, maybe there is a non-standard way to create io-stream from FILE * ? Is there any boost::ifstream with MSVC like extension for Windows? Kornel Kisielewicz Unfortunately, there's no standard way to do that, although C++0x
