Well, you know, this is possible because your browser can display them. On Windows, you can use the charmap.exe applet to detect your Unicode code points:
- ♠ = 0x2660
- ♣ = 0x2663
- ♥ = 0x2665
- ♦ = 0x2666
The challenge is to get a C / C ++ program to display them. This will not be possible in any form of non-platform unless you use a cross-platform user interface library such as Qt or wxWidgets. In the Windows GUI program, you can do this as in the WM_PAINT message handler:
case WM_PAINT: {
hdc = BeginPaint(hWnd, &ps);
HFONT hFont = CreateFont(16, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, L"Arial Unicode MS");
HGDIOBJ oldFont = SelectObject(hdc, hFont);
RECT rc = {0, 0, 666, 16};
DrawTextEx(hdc, L"\x2660\x2663\x2665\x2666", -1, &rc, DT_LEFT, 0);
SelectObject(hdc, oldFont);
DeleteObject(hFont);
EndPaint(hWnd, &ps);
}
break;
