当我尝试使用 Wingdings 字体(或其他符号字体)时,文本显示为矩形而不是正确的文本。如何让正确的字符显示?
import java.awt.*;
import javax.swing.*;
public class WingdingsFontDisplay extends JFrame
{
    public static void main(String[] args)
    {
        new WingdingsFontDisplay();
    }
    public WingdingsFontDisplay()
    {
        this.setSize(500,150);
        this.setTitle("Fun with Fonts");
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //This shows that I do have "Wingdings" available
        GraphicsEnvironment g;
        g = GraphicsEnvironment.getLocalGraphicsEnvironment();
        String[] fonts = g.getAvailableFontFamilyNames();
        for(String f : fonts)
        {
            System.out.println(f);
        }
        //Displaying text in the Wingdings font shows rectangles
        JLabel wingdingsText = new JLabel("All work and no play makes Jack a dull boy");
        Font f1 = new Font("Wingdings", Font.PLAIN, 14);
        wingdingsText.setFont(f1);
        this.add(wingdingsText, BorderLayout.NORTH);
        //Displaying text in Arial works correctly
        JLabel arialText = new JLabel("All work and no play makes Jack a dull boy");
        Font f2 = new Font("Arial", Font.PLAIN, 14);
        arialText.setFont(f2);
        this.add(arialText, BorderLayout.SOUTH);
        this.setVisible(true);
    }
}
