The em of Ja Hiragana can't be selected from the choicebox by the keyboard input

 (1) Working environments
 OS : Solaris2.6, Windows NT4.0/95
 JDK : JDK1.1.8, JDK1.2 fcs
 Window : CDE
 Japanese Input : Atok7, Atok8
 
 (2) Symtom
 Step1: Read a html file ComboSelect.html including the applet.
         (You can also access http://speed.japan/~kyo/ComboSelect.html
          to see the symtom. The Java plugin1.2 is needed.)
 Step2: Focus the ChoiceBox.
 Step3: You can select both alphabet and Japanese Hiragana items
         in the box by mouse or by arrow-keys.
         However, you may find the em of Japanese Hiragana can't be
         selected by the keyboard input directly, although the alphabet
         items can be.
         
Notice: If you run the testcase as an application type
        on IBM VisualAge for Java 2.0,
        there is no problem to select the em of Japanese Hiragana
        by the keyboard input directly.

We find the slection by key-board is related to
the JComboBox.DefaultKeySelectionManager.
JComboBox's selection is conducted by selectionForKey method of
JComboBox.DefaultKeySelectionManager interface, however this method
isn't called when we input an em letter on the keyboard. So we ask
whether the input of an em letter of Japanese Hiragana on the keyboard
is refused on the jvm level, or even KeySelectionManager is not called
when an em letter is inputed by key-board.
