UNICODE characters can not be displayed properly when you use a Monospaced font:

   FE68 - full width Backslash
   FFE5 - Full width Yen sign
   FFE0 - Full width Cent sign
   FFE1 - Full width Pound sign

You can recreate this problem with SymbolTest demo applet or with the attached
code (thanks to the licensee support group in Japen for this) :-

O/S version: WindowsNT - Taiwan

import java.awt.*;

public class test extends java.applet.Applet {
        TextField text;
        Button button;
        static String str = "\uFE68\uFFE5\uFFE0\uFFE1";

    public void init() {

        text = new TextField(str, 10);
        add(text);

        button = new Button(str);
        add(button);
    }
}
