_tprintf with Unicode characters in a console app

c++, console-application, unicode, winapi

Solution

By default, windows console does not process wide characters. Probably the simplest way to enable that functionality is to call `_setmode`:

_setmode(_fileno(stdout), _O_WTEXT);

See MSDN for the required includes, usage examples, and other available modes.

Problem

I'm doing this simple output from a Unicode-built console application (using C++ and Visual Studio 2008). This code is intended to run on Windows: ``` _tprintf(L"Some sample string\n"); ``` Everything works fine. But if I add an non-ASCII character in there: ``` _tprintf(L"Some sample € string\n"); ``` what gets output to the console is everything until that character: Some sample What am I doing wrong here?
