Question

我在游戏中使用LWJGL和Slick Util。但现在我无法制作俄语语言环境，因为slick.TrueTypeFont不会呈现西里尔字母（ЯиssiaпVodка，Сомяаd，Уер）。有人知道如何解决它吗？

为了解决这个问题我做了这个方法：

private Texture letter(char i) {
        if (letter[(int) i] != null) {
            return letter[(int) i];
        } else {
            /*
             Making empty buffer to get character's width.
             */
            BufferedImage im = new BufferedImage(1, 1, BufferedImage.TYPE_BYTE_BINARY);
            Graphics g = im.getGraphics();
            FontMetrics fm = g.getFontMetrics(f);
            int w = fm.charWidth(i);
            int h = fm.getHeight() * 5 / 4;
            /*
             Making the java.awt.BufferedImage with character.
             */
            if (w == 0) {
                w = 1;
            }
            im = new BufferedImage(w, h*2, BufferedImage.TYPE_4BYTE_ABGR);

            Graphics2D g2 = (Graphics2D) im.getGraphics();
            g2.setFont(f);
            g2.setColor(java.awt.Color.WHITE);

            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                    RenderingHints.VALUE_ANTIALIAS_ON);
            g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
                    RenderingHints.VALUE_INTERPOLATION_BICUBIC);

            g2.drawString(i + "", 0, h);

            {
                /*
                 Converting image to the Texture.
                 */
                try {
                    ByteArrayOutputStream os = new ByteArrayOutputStream();
                    ImageIO.write(im, "png", os);
                    InputStream is = new ByteArrayInputStream(os.toByteArray());
                    Texture t = TextureLoader.getTexture("PNG", is);
                    letter[(int) i] = t;
                    return t;
                } catch (IOException ex) {
                    System.out.println("\"" + i + "\" isn't loaded.");
                }
                return null;

            }
        }
    }
