9968	[filesystem] Streams don't handle unicode file name on Windows	mike@…	Beman Dawes	"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."	Bugs	new	To Be Determined	filesystem	Boost 1.55.0	Problem		mingw
