On Win32 platform (tested NT4.0 ja), following SJIS code is converted to different unicode than MicroSoft mapping. These are identail character, but has two different character code.

        These 5 character is recognized incorrectly yet.

                                        MS- JAVA
        Name SJIS UNICODE UNICODE
        ------------------------------------------------
        palarell sign 0x8161 0x2225 0x2016
        fullwidth minus 0x817c 0xff0d 0x2212
        cent sign 0x8191 0xffe0 0x00a2
        pound sign 0x8192 0xffe1 0x00a3
        mathematical not sign 0x81ca 0xffe2 0x00ac

palarell sign and fullwidth minus are different character conversion
between MS-Windows and Java.
Other 3 characters are mapped to Latin-1 category by Java, but
mapped to FullWidth Form category by MS-Windows.

Sample Program as follows. Upper testfield is awt.TextField,
Lower is awt.swing.JTextField. When pushed enter key in each textfield,
the text it has is displayed into TextArea, Label and System.out.

class GetSetString extends Frame implements ActionListener {
  JTextField jtf;

    if (e.getSource() == jtf)
      dataText = jtf.getText();
    else
      dataText = tf.getText();
    ta.setText( dataText );
    l.setText( dataText );
    System.out.println( "data: "+dataText );
  }

    obj.addWindowListener( new WindowAdapter(){
      public void windowClosing( WindowEvent e ){ System.exit(0);}
    });
