Reproduce:
    - Extract the test case as attached.
    - Execute it.
      % cd swingtest/classes
      % java SwingTest -command aaa
    - Move the caret to TextField/TextArea.
    - Enter the '\u301c' character.

You can see the box character which can't be handled.
It's not only on TextField/TextArea but also on the other
swing components. Attached as "swing_u301c.jpg" is a
