RFE: Sol7: Many characters can't display in TextArea on ja_JP.UTF-8

Many characters including Hiragana can't be displayed in TextArea on ja_JP.UTF-8.

Configuration:
JDK1.1.8 build "C"
Solaris 7, CDE1.3, ja_JP.UTF-8

I can't see this problem on EUC (ja locale).

How to reproduce:

1) run the test program.

%java CharViewMultiLine

2) the test window comes up and set 3040 (4E00, FF60) to
the code point.

3) many characters are not displyed in TextArea.

Please see the attached utf8awt.GIF to make sure the appearance.
The upperleft window is the test window.
If you select text in TextArea and hit "copy", then "paste" in
the text editor at the lower right window, you can see the characters
that you can't see in the upper left window.

Test programs are stored as an attachment.
