Java HotSpot(TM) Client VM (build 1.3.0rc3-Z, mixed mode)

  From the program below, I can display the Chinese characters when I set the
fonts for each label components. However, the JOptionPane does not allowed me
to set the fonts so that the Chinese characters cannot display correctly.

1. javac Sample.java (The program listed below)
2. java Sample
3. type in the username and password, then press the button
4. The chinese characters in JOptionPane will be displayed with distortion

The following is the codes of Sample.java
_______________________________________________________________________________
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;

public class Sample {

    JTextField textField = null;
    JPasswordField passwordField = null;

    public static void main(String[] argv) {
       new Sample();
    }

    Sample() {
// spwan a timer thread

textField = new JTextField(18);
Font font = new Font("Dialog", Font.PLAIN, 12);
JLabel label1 = new JLabel("輸入用戶名稱 (例:hgc12345)");
label1.setFont(font);
textField.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});

final JFrame f = new JFrame("核對用戶身份");
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
f.setBounds ( 250, 250, screenSize.width - 300*2,
screenSize.height - 300*2 );

JLabel label2 = new JLabel("輸入用戶密碼 (例:P123456A)");
label2.setFont(font);
passwordField = new JPasswordField(18);
passwordField.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {

}
});

JButton button = new JButton("確定");
button.setFont(font);

button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
JPanel labelPane = new JPanel();
labelPane.setLayout(new BoxLayout(labelPane,BoxLayout.Y_AXIS));
labelPane.add(Box.createRigidArea(new Dimension(0, 3)));
labelPane.add(label1);
labelPane.add(Box.createRigidArea(new Dimension(0, 7)));
labelPane.add(label2);

JPanel fieldPane = new JPanel();
fieldPane.setLayout(new BoxLayout(fieldPane,BoxLayout.Y_AXIS));
fieldPane.add(textField);
fieldPane.add(Box.createRigidArea(new Dimension(0, 5)));
fieldPane.add(passwordField);

JPanel buttonPane = new JPanel();
buttonPane.setLayout(new BoxLayout(buttonPane, BoxLayout.X_AXIS));
buttonPane.setBorder(BorderFactory.createEmptyBorder(10, 0, 0,
0));
buttonPane.add(Box.createHorizontalGlue());
buttonPane.add(button);

JPanel contentPane = new JPanel();
contentPane.setBorder(BorderFactory.createEmptyBorder(10,10, 10, 10));
contentPane.setLayout(new BorderLayout());
contentPane.add(labelPane, BorderLayout.WEST);
contentPane.add(fieldPane, BorderLayout.CENTER);
contentPane.add(buttonPane, BorderLayout.SOUTH);

f.setContentPane(contentPane);
f.pack();
f.setVisible(true);

I have uninstalled the Java 2 SDK SE 1.3 and use Java 2 SDK SE 1.2.2 instead so
I cannot reproduce this message again.

I just run the jfc Swingset2 demo in jdk1.3 on Traditional Chinese Windows 98.
All the Chinese fonts are not properly displayed, so I uninstalled the 1.3
version and use the 1.2.2 instead. Please make the fonts display properly in
all platforms or NOT TO MAKE IT INTERNATIONALIZE! Further and frankly speaking,
I could speak fluent Chinese but I really could not understand the Chinese
messages generated by the compiler. Please hire a person who has a better
Chinese background to write the messages. Thanks.

java -1.3

Running the same code in Win NT 4.0 and Win98,
the Chinese characters appeared correctly in Win NT 4.0
but showed up garbled in Win98.

chinese.setFont(new Font("\u7d30\u660e\u9ad4", Font.PLAIN, 14));
chinese = new JButton("\u7e41\u9ad4\u4e2d\u6587");

It seems to me that JDK 1.3 have some difficulity when displaying chinese
character in JLabel and JButton.

Included is a program which reproduce the bug.

In the program, I pass in the same Unicode string into Label, JLabel, JButton,
and JtextField. Apparently, the text displayed in the JtextField and Label are
all readable. Those in Jlabel and Jbutton, however, are unreadable.

I also do another experientment by encoding the text into Big 5 and display
their code. It also show some differents between Jlabel and JtextField.

Something instresting I found is that it can be display correctly if I use the
Jlabel.setFont method. But Jlabel and Jbutton seems can’t get the setting in
the font.properties while JtextField is displaying properly.
