Can I write:
boost::filesystem::fstream
f("שלום.txt",std::ios_base::out);
When "שלום.txt" is UTF-8 string and
Unicode file name will be created?
If so, way to go.
In v3, yes.
There are some caveats, but it should work, and there are some fairly similar test cases passing all compilers.
This is not what I'd understood from our previous discussion. I was under the impression filesystem v3 running on Windows would take this narrow path string and convert it to UTF-16 using the *local code page*. This means the example above would only work if the computer in question were set to Hebrew.

Did I misunderstand?
Yes, you did. When I was talking about UTF-8 I mean Unicode and not subset. For example, in my case I want to open a file std::ofstream f("سلام-שלום-Peace-Мир.txt") I can't do this on Windows (only) So I open it with nowide::ofstream f("سلام-שלום-Peace-Мир.txt") And it works on Windows as well. The only operating system that does not allow **any** file being opened with std::fstream::open or std::fopen is Windows and this is what the library wants to fix. You can download my code there: http://art-blog.no-ip.info/files/nowide.zip It gives you: STL's nowide::ifstream nowide::ofstream nowide::fstream nowide::filebuf STDlib's nowide::fopen nowide::freopen nowide::remove nowide::rename All using UTF-8 strings (as it usually work on all modern operating systems) Artyom
