Problem : Japanese Character Support

Hello,

I have one problem. I am working on java and postgre sql.
The data in postgre sql is in japanese
When i used JDBC code in java like select statement then i
get the resultset but in that resultset instead of
japanese data , empty string is coming so i am not getting
japanese data in java from postgre sql.
Its not giving error but return empty string. But, when i
used english data, its working fine

What could be the problem?
Is it that postgre's JDBC driver is not supporting
japanese character.

Waiting for early reply.
