String containing Unicode \u0700 - \u206F characters are not displayed correctly.

OS: WindowsNT4.0 (Japanese), Windows98 (Japanese)
JDK version: 1.2.2-004 - 006, 1.3, 1.3.1 and 1.3.0_01
(There is no problem on versions earlier than 1.2.2 and the latest version 1.4.0beta-b40)
Method: Graphics.drawString(String s) and Graphics2D.drawString(String g)

To reproduce this bug, please compile test program below and run through appletviewer.
This program displays two lines of strings. Upper line contains only ascii characters.
Lower line contains Unicode \u2015 character. Both two lines will appear at first, but after
we hide strings by another window and slide that window a little bit, the lower line will not
be repainted.

===================== test.java ========================================================
public class test extends Applet{
  public void paint(Graphics g){
    //Graphics2D g2d = (Graphics2D)g;
    //g2d.setFont(new Font("Dialog", Font.PLAIN, size));
    //g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    g.drawString("abcdefghijeklmnopqrstuvwxyz",10,30);
    g.drawString("abcdefghijekl\u2015mnopqrstuvwxyz",10,50);
  }
}

This problem also occurs with Graphics2D.drawString method.
To reproduce this, please uncomment 3 comment lines in test.java and change variable
name g to g2d.
