------------------------------+------------------------
 I want to read / write a file with a unicode file name using boost
 filesystem, boost locale on Windows (mingw).

 This is my code:

 #include <boost/locale.hpp>
 #define BOOST_NO_CXX11_SCOPED_ENUMS
 #include <boost/filesystem.hpp>
 #include <boost/filesystem/fstream.hpp>
 namespace fs = boost::filesystem;

 #include <string>
 #include <iostream>

 int main() {

   std::locale::global(boost::locale::generator().generate(""));
   fs::path::imbue(std::locale());

   fs::path file("äöü.txt");
   if (!fs::exists(file)) {
     std::cout << "File does not exist" << std::endl;
   }

   fs::ofstream(file, std::ios_base::app) << "Test" << std::endl;
 }

 The fs::exists really checks for a file with the name äöü.txt. But the
 written file has the name äöü.txt.

 Reading gives the same problem. Using fs::wofstream doesn't help either,
 since this just handles wide input.

 So it seems the behaviour of fs::ofstream is off.
