Hi folks,
I'm hoping someone can tell me the magic to get java (6 or 7) to display unicode chars under ms-windows?

This is a standalone program, not an applet:

The program itself works; I know this, because it displays fine under macos.
Unfortunately, the exact same jar file displays empty boxes instead of nice kanji chars, under ms-windows. Using java version 6 or 7.

Looking in the font properties type files, it seems like they are referencing ms-gothic and ms-mincho fonts. which ARE present on the system.
I see ms-gothic and ms-mincho in Control panel->fonts
And my browser successfully displays unicode pages such as

So... why isnt java displaying unicode properly???

Some years ago, it was neccessary to download a special "international" version of java on windows, to display 16-bit-wide fonts.
but there does not even seem to be that option any more.
So.. what should I do?

I copied some text from into Libre Office. I saved
the text as UTF-8. I used the program below to display it. It isn't
quite correct though, I get a dot before the text that wasn't on the web
page. Other than that it works fine.

import java.awt.*;
import java.awt.event.*;
import java.nio.charset.*;
import javax.swing.*;

public class test extends JPanel {
     private char[] buffer = new char[256];
     private int n;

     public test() {
         setPreferredSize(new Dimension(320,240));
         try {
             FileInputStream fis = new FileInputStream("xxx");
             InputStreamReader isr = new InputStreamReader(fis,"UTF-8");
             n =,0,256);
         } catch (IOException ioe) {

     public void paintComponent(Graphics g) {
         g.setFont(new Font("MS Mincho",Font.PLAIN,12));

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame();
                 f.add(new test(),BorderLayout.CENTER);
