[CMake] Unicode path wrecks havoc with VS2013 generator

[Nagy-Egri Máté Ferenc]

Hi!


I have the following issue, which I do not know whether it is an issue of CMake or Visual Studio. When I try to generate a Visual Studio project under a path that contains unicode characters, VS fails to compile the simple test file and thus CMake terminates project generation. Visual Studio does have some issues with projects under unicode paths, but generally things work. (For eg. the C++AMP call tree generator breaks, therefore no C++AMP project can be built in such paths) I develop all my applications in my Skydrive folder which is under the Users folder, and since my name holds unicode characters, I have no control over mw home folder under Win 8 if I have a Live-ID user in the OS. This is what happens:


C:\Users\MátéFerenc\SkyDrive\Develop\Active\GridRipper\VS2013>cmake -G "Visual Studio 12" -D USE_OPENCL:BOOL=ON ../

-- The CXX compiler identification is MSVC 18.0.21005.1

-- Check for working C compiler using: Visual Studio 12 -- broken
CMake Error at C:/Kellekek/CMake 2.8/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:61 (message):
  The C compiler "C:/Kellekek/Microsoft Visual Studio 12.0/VC/bin/cl.exe" is
  not able to compile a simple test program.


  It fails with the following output:

The hungarian part of the string found in the error message “project file could not be loaded. Érvénytelen karakter az adott kódolásban. Sor: 60, pozíci : 83.” means invalid character in the given encoding Line 60, position 83


If I use the NMake generator, everything works fine. Output is:

Is this the right place to post this issue? Visual Studio in most cases works under unicode paths, but in this case VS seems to complain about mal-encoded characters in the project file.


Any ideas?
