118[Sol7] Hang when dispaying \u0080 in the title bar on ja_JP.UTF-8

When trying to display \u0080 on the title bar of the window,
the program hangs up.

Configuration:
JDK1.1.8 build "C"
Solaris 7, CDE1.3, ja_JP.UTF-8

This program works file on ja locale (EUC).

How to reproduce:

1) compile ViewTitleBar.java

import java.awt.*;
import java.awt.event.*;

public class ViewTitleBar extends Frame implements ActionListener {
  Button bQuit;

  public ViewTitleBar() {
    super("ViewTitleBar");
    add(bQuit = new Button("Quit"));
    bQuit.addActionListener(this);
setTitle("test x0080:\u0080");
  }
 
  public void actionPerformed(ActionEvent evt) {
    if(evt.getSource() == bQuit) System.exit(1);
  }

2) run ViewTitleBar and got a hang up.
