java - 获取异常 FontFormatException Unsupported sfnt resources/fonts/OpenSansEmoji.ttf

Question

我在资源/字体文件夹中有 OpenSansEmoji.ttf 和其他字体，如 Proxima Nova Regular.otf，对于 Proxima Nova Regular.otf/Proxima Nova Alt Light.ttf，它没有给我异常(exception)，OpenSansEmoji.otf 也没有，但是对于 OpenSansEmoji.ttf，它给了我以下异常，我该怎么办？

    SEVERE: null
    java.awt.FontFormatException: Unsupported sfnt resources/fonts/OpenSansEmoji.ttf

我的代码在这里

  try {
            FontUtils.registerFonts(fonts);
        } catch (IOException | FontFormatException ex) {
            Logger.getLogger(Java2D.class.getName()).log(Level.SEVERE, null, ex);
        }



  public static void registerFonts(List<String> paths) throws IOException, FontFormatException {

        for (String path : paths) {
            String fName = "resources/fonts/" + path;
            GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
            ge.registerFont(Font.createFont(Font.TRUETYPE_FONT, new File(fName)));
        }
    }

根据维基百科，http://en.wikipedia.org/wiki/SFNT是一种字体的容器格式，由 TrueType 等使用。但是，Java 不支持所有 SFNT 字体，仅支持 TrueType。

来自 sun.font.TrueTypeFont javadoc:

TrueTypeFont is not called SFntFont because it is not expected to handle all types that may be housed in a such a font file.

基本上这意味着您的字体虽然以 .ttf 文件结尾，但实际上不是 TrueType，您不能使用它。可能是它是 OpenTypeFont，Java 不支持它。您可以尝试转换字体；谷歌显示了许多可能性。
