UNICODE and JDBC Driver

I'm working on a project where we need to be able to support characters such
as trademark, copyright and various accents.

Initially our database was created with the SQL character encoding. Data was
entered using an access database connected by ODBC and everything was fine.
The characters show correctly in the Access application.

However, the web portion using the JDBC driver cannot display these
characters and has all sorts of problems. DB Visualizer also complains.

Consequently we dumped the database contents, recreated it with the UNICODE
character set and restored the contents. Now the database and the JDBC
driver are both using UNICODE but it still doesn't work.

We're despairing that we'll have to tell our client they can't use extended
characters. Please tell me this is not the case! Help!!!
