Output Unicode strings in Windows console

by

I have verified a solution here using Visual Studio 2010. Via this MSDN article and MSDN blog post. The trick is an obscure call to _setmode(..., _O_U16TEXT).

Solution:

#include <iostream>
#include <io.h>
#include <fcntl.h>

int wmain(int argc, wchar_t* argv[])
{
    _setmode(_fileno(stdout), _O_U16TEXT);
    std::wcout << L"Testing unicode -- English -- Ελληνικά -- Español." << std::endl;
}
