C store and print wchar_t

Question

I want to store a string with characters from extend ascii table, and print them. I tried:

wchar_t wp[] = L"Росси́йская Акаде́мия Нау́к ";
printf("%S", wp);

I can compile but when I run it, nothing is actually displayed in my terminal.

Could you help me please?

Edit: In response to this comment:

wprintf(L"%s", wp);

Sorry, I forgot to mention that I can only use write(), as was only using printf for my first attempts.

Answer 1

If you want wide chars (16 bit each) as output, use the following code, as suggested by Michael:

wprintf(L"%s", wp);

If you need utf8 output, you have to use iconv() for conversion between the two. See question 7469296 as a starting point.

Answer 2

You need to call setlocale() first and use %ls in printf():

#include <stdio.h>
#include <wchar.h>
#include <locale.h>

int main(int argc, char *argv[])
{
    setlocale(LC_ALL, "");
    // setlocale(LC_ALL, "C.UTF-8"); // this also works

    wchar_t wp[] = L"Росси́йская Акаде́мия Нау́к";
    printf("%ls\n", wp);

    return 0;
}
