Description

Name: gvC48267			Date: 01/13/98


In Japanese-Windows95 system,
JDK1.2b2(win32)'s TextArea and TextField cannot display
non-English language strings.

I can input Japanese strings in TextArea and TextField correctly.
And they are displayed correctly.
But Japanese strings (Unicode escaped) in a source program
are not displayed in TextArea and TextField correctly.
Another Components(Button, etc) can be displayed correctly.
BugID 4060931 seems a Solaris bug.
My bug can be evaluated by the same program in the bug report.

My test program is following.
