On Japanese Win95, TextArea.insert*/append*/replace* operations corrupt
Japanese text. The following test program reproduces the problem.

import java.awt.* ;
public class test extends java.applet.Applet {
    Frame window ;
    public void init() {
window = new MyFrame("test case of java.awt.ScrollPane") ;
window.resize(850,450) ;
window.show() ;
    }
}

class MyFrame extends Frame {
    TextArea ta1 ;
    TextArea ta2 ;
    int buttonDown=0 ;

    MyFrame(String title) {
super(title) ;
ta1 = new TextArea("\u30c6\u30b9\u30c8\u3060\u3088\u30fc\u3093") ;
add(ta1) ;

ta2 = new TextArea("\u30c6\u30b9\u30c8\u3060\u3088\u30fc\u3093") ;
add(ta2) ;

Button bt = new Button(" \u6b21 \u3078 ") ;
add(bt) ;

setLayout(new FlowLayout(FlowLayout.CENTER)) ;
    }

    public boolean action(Event evt, Object arg) {
if (evt.target instanceof Button) {
String label = (String) arg ;
if (label.equals(" \u6b21 \u3078 ")) {
nextAction() ;
}
}
return true ;
    }

    public void nextAction () {
switch (buttonDown) {
case 0 :
ta1.appendText(" test dayo-n") ;
ta2.insertText("test dayo-n ",0) ;
break ;
case 1 :
ta1.append(" \u30c6\u30b9\u30c8 \u3060\u3088\u30fc\u3093") ;
ta2.insert("\u30c6\u30b9\u30c8 \u3060\u3088\u30fc\u3093 ",0) ;
break ;
            case 2 :
ta1.append(" test dayo-n") ;
ta2.insert("test dayo-n ",10) ;
break ;
case 3 :
ta1.appendText(" \u30c6\u30b9\u30c8 \u3060\u3088\u30fc\u3093") ;
ta2.insertText("\u30c6\u30b9\u30c8 \u3060\u3088\u30fc\u3093 ",23) ;
break ;
default :
buttonDown-- ;
}
buttonDown++ ;
    }
}
