      Description

      Name: skT45625 Date: 08/07/2000


      java version "1.3.0beta_refresh"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta_refresh-b09)
      Java HotSpot(TM) Client VM (build 1.3.0beta-b07, mixed mode)


      Platform: x86-architecture, Linux kernel 2.2.16 (based on RedHat 6.0 with many
      updates), XFree86 3.3.5
      Java: JDK 1.2.2_006 or JDK 1.3.0beta_refresh
      System Enveroment:
      LANG=ru
      LC_ALL=ru_RU.KOI8-R
      Java property:
      file.encoding=KOI8-R

      For cyrillic input in XFree86 used Xkb. In Xkb setted 3 keyboard layout
      ("US/ASCII", "KOI8-R", "Cyrillic" ). The part of file with defines of symbols
      for Cyrillic 'A':
      ----------------- start -----------------
          key <AC04> { [ f, F ],
                              [ 0xc1, 0xe1 ],
                              [ Cyrillic_a, Cyrillic_A ] };
      ----------------- end -----------------
      For switching keyboard layouts used ISO_Group.

      For test of input used this application:

      ----------------- start -----------------
      import java.awt.*;
      import java.awt.event.*;
      import javax.swing.*;
      import java.util.*;

      public class ex {
        boolean packFrame = false;

        public ex() {
          ex_frame frame = new ex_frame();
          if (packFrame) {
            frame.pack();
          }
          else {
            frame.validate();
          }
          frame.setVisible(true);
        }

        public static void main(String[] args) {
          try {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
          }
          catch(Exception e) {
            e.printStackTrace();
          }

          new ex();
        }

        public class ex_frame extends JFrame {
          JPanel contentPane;
          GridLayout gridLayout1 = new GridLayout();
          JTextField jTextField1 = new JTextField();
          JButton jButton1 = new JButton();
          JTextField jTextField2 = new JTextField();

          public ex_frame() {
            enableEvents(AWTEvent.WINDOW_EVENT_MASK);
            try {
              jbInit();
            }
            catch(Exception e) {
              e.printStackTrace();
            }
          }

          private void jbInit() throws Exception {
            gridLayout1.setRows(2);
            contentPane = (JPanel) this.getContentPane();
            contentPane.setLayout(gridLayout1);
            jTextField1.setToolTipText("input character here");
            jTextField1.setDisabledTextColor(Color.gray);
            jTextField1.setHorizontalAlignment(SwingConstants.CENTER);
            jTextField1.addKeyListener(new java.awt.event.KeyAdapter() {
        
              public void keyTyped(KeyEvent e) {
                jTextField1_keyTyped(e);
              }
            });
            jTextField2.setToolTipText("Unicode code of input character");
            jTextField2.setEditable(false);
            jTextField2.setHorizontalAlignment(SwingConstants.CENTER);
            contentPane.add(jTextField1, null);
            contentPane.add(jTextField2, null);
          }

          protected void processWindowEvent(WindowEvent e) {
            super.processWindowEvent(e);
            if (e.getID() == WindowEvent.WINDOW_CLOSING) {
              System.exit(0);
            }
          }

          void jTextField1_keyTyped(KeyEvent e) {
            jTextField2.setText( Integer.toHexString( e.getKeyChar() ) );
          }
        }

      }
      ----------------- end -----------------

      In upper TextField input characters, in buttom TextFiled see Unicode code of
      last input character in Hex.

      For key with Cyrrilic 'A' (UNICODE code - 0x0410) we see:
      in JDK 1.2.2_006
      layout 1: 46 (correct for all - latin F)
      layout 2: e1 (correct for KOI8-R, but incorrect for UNICODE)
      layout 3: 6e1 (correct for Cyrillic_A defined in X11/keysymdef.h, but incorrect
      for UNICODE - 0x06xx - arabic page)

      in JDK 1.3.0beta_refresh
      layout 1: 46 (correct for all - latin F)
      layout 2: e1 (correct for KOI8-R, but incorrect for UNICODE)
      layout 3: e1 (correct for KOI8-R, but incorrect for UNICODE)

      PS: sorry for bad english.
