Sometimes you need to determine if you have Java font support for a particular character in Unicode. This is what I use when I need to find out. The source code is HERE

import java.awt.*;

public class CanDisplay {
    static String currentFontName = "";

    public static void main(String[] args){

        if(args.length < 1){
            System.out.println("Usage: java CanDisplay <Unicode character, e.g. 0044>");
        char c = (char)Integer.parseInt(args[0],16);
        System.out.println("Checking on character " + c);
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        Font[] fonts = ge.getAllFonts();

        for(int i = 0;i < fonts.length ;i++){
            String fontName = fonts[i].getFontName();
             * Assume that if a glyph is contained in a certain typeface,
             * then its first font will be able to display it. Otherwise
             * this iteration can take a long time.
            if (fontName.equals(currentFontName)){
            else {
                currentFontName = fontName;
            if (fonts[i].canDisplay(c)){
                // Just take the first one as this iteration can take a long time!
        System.out.println("Font not found");
