How to change the character set in order to be able to view hebrew via ODBC

Hello,

Can anyone walk me through the steps I need to take in order to change

the DB character set so I will be able to view unicode sets (hebrew) directly

via ODBC connection (Via SAP it works fine and is configured correctly)

My database is Oracle Release 9.2.0.7.0 , I am running it on Windows 2003

and my version of SAP R/3 is 4.6c

When I connect to the DB directly via ODBC connection I can't see the hebrew characters (code page 1800 in SAP)

I tried changing the NLS_LANG settings on the server registery but this did not help.

Thanks,

Mark
