How can I use a foreign language char in Swing

[Ricky]

I installed J2SDK 1.4.0 several days ago. I need to get some strings from
database which stored in GB2312 encode method, and display it using Swing. I
got correct result in Windows2000(Use China as default region and GB2312 as
encode method.) While I¡¡run it on Windows(English Edition), all I can see
is ?????.

What should I do? I think ResourceBoundle can't help me. Is there any other
method can help me?
