    JFrame frame = new JFrame();

    Java2D_UDC comp = new Java2D_UDC();
    frame.getContentPane().add(comp);

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setBounds(0, 0, 400, 60);
    frame.setTitle("Font Test");
    frame.setVisible(true);
  }

  public void paintComponent(Graphics g){
    Graphics2D g2d = (Graphics2D)g;
  
   Font font = new Font(Font.MONOSPACED, Font.PLAIN, 16);
        g2d.setFont(font);
  
String testStr="UDC:\uE000\uE001\uE002";
