问题描述

如何打印 C ++中的这些UTF-8字符？

推荐答案

。在Windows上，您可以使用charmap.exe小程序来发现其Unicode代码点：

Well, you know it is possible because your browser could render them. On Windows you can use the charmap.exe applet to discover their Unicode code points:

• ♠= 0x2660


• ♣= 0x2663


• ♥= 0x2665


• ♦= 0x2666

• ♠ = 0x2660
• ♣ = 0x2663
• ♥ = 0x2665
• ♦ = 0x2666

挑战是获得一个C / C ++程序来显示它们。这不可能在任何种类的非平台特定的方式，除非你使用跨平台UI库，如Qt或wxWidgets。在Windows GUI程序中，您可以在WM_PAINT消息处理程序中这样做：

The challenge is to get a C/C++ program to display them. That's not going to be possible in any kind of non-platform specific way unless you use a cross-platform UI library like Qt or wxWidgets. In a Windows GUI program you can do it like this 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;
