Printing a Unicode Symbol in C

by

Two problems: first of all, a wchar_t must be printed with %lc format, not %c. The second one is that unless you call setlocale the character set is not set properly, and you probably get ? instead of your star. The following code seems to work though:

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

int main() {
    setlocale(LC_CTYPE, "");
    wchar_t star = 0x2605;
    wprintf(L"%lc\n", star);
}

And for ncurses, just initialize the locale before the call to initscr.
