How can I print card suit characters in C Win32 console application? - c

Question

I have seen a few questions on how to print these characters but none of the methods appear to be working. I suspect it is because I making a Win32 console application based on some of the comments I read.
Here is an example of what I have tried in my code currently. It only prints question mark boxes, or if I change it around I get question marks or random symbols.
I have tried defining these at the top.
#define SPADE '\x06'
#define CLUB '\x05'
#define HEART '\x03'
#define DIAMOND '\x04'
inside function, these are some of the things I've tried. I have left S,D,H,C in case I can't figure it out.
printf("%lc", SPADE);
//printf("♠");
//printf("S");
printf("%lc", HEART);
//printf("♥");
//printf("H");
printf("%lc", DIAMOND);
//printf("♦");
//printf("D");
printf("%lc", CLUB);
//printf("♣");
//printf("C");

UTF-16 wchar_t and wide characters functions are needed in Windows.
#include <windows.h>
int main()
{
DWORD n;
HANDLE hout = GetStdHandle(STD_OUTPUT_HANDLE);
const wchar_t *buf = L"♠♥♦♣\n";
WriteConsoleW(hout, buf, wcslen(buf), &n, 0);
return 0;
}
The following code will compile with Visual Studio:
#include <stdio.h>
#include <io.h> //for _setmode
#include <fcntl.h> //for _O_U16TEXT
int main()
{
_setmode(_fileno(stdout), _O_U16TEXT);
wprintf(L"♠♥♦♣\n");
return 0;
}
After setting the mode to UTF-16, you have to call _setmode(_fileno(stdout), _O_TEXT) if you wish to use printf again.
