How to output Cyrillic in C (not C++)?

Question

C++ / C#

How to force the C compiler (Visual Studio 2010) to output Cyrillic?

Answer 1

Write in main:
Also add the locale library
#include <locale.h>

Answer 2

Head-on solution: you need to switch the editor to a different encoding (to the one in which the text will be output to the console).

Answer 3

if it's POSIX then printf("That's a UTF-8 string, Carl\n")
