Comment(by anonymous):

 Agreed...
 On Windows with msvc 2008, we end up doing something like:


 {{{
 wchar_t wideFile = L"example.txt"; // file we want to open with boost
 std::string  fileName;

 // first call gets buffer size
 int bufSize = ::WideCharToMultiByte(CP_ACP, 0, wideFile, -1,
                                     NULL, 0, NULL, NULL);

 fileName.resize (bufSize);

 // second call converts the filename
 int iRet = ::WideCharToMultiByte(CP_ACP, 0, wideFile, -1,
                                  &fileName.at(0), bufSize, NULL, NULL);

 boost::iostreams::file_sink(fileName.c_str(), ...)
 }}}
