我正在尝试使用raylib显示包含西里尔字符的字符串。所以我加载了一个代码点如下的字体：

int codepoints[512] = { 0 };
for (int i = 0; i < 95; i++) codepoints[i] = 32 + i;
for (int i = 0; i < 255; i++) codepoints[96 + i] = 0x400 + i;
Font font = LoadFontEx("arial.ttf", 32, codepoints, 512);

如果我画font。在屏幕上，我可以看到ASCII和西里尔字符。然而，我无法使DrawTextEx呈现这些字符，但DrawTextCodepointworks as I expected it to。例如：

    BeginDrawing();
    ClearBackground(RAYWHITE);

    DrawTextEx(font, "Ё", (Vector2) { 10, 70 }, 32, 0, BLACK); // draws a ? symbol
    DrawTextEx(font, "\u0401", (Vector2) { 10, 40 }, 32, 0, BLACK); // draws a ? symbol
    DrawTextCodepoint(font, 0x0401, (Vector2) { 10, 10 }, 32, BLACK); // draws Ё, as expected       
    EndDrawing();
