Some 8-bit data are appearing as '?' mark when viewed thro' Oracle Forms against oracle 8.1.5. the NLS_CHARECTER set is set correct as:
on the server side it's :AR8ISO8859P6
on the clients: AMERICAN_AMERICA.AR8MSWIN1256.

However still it appears as '?'. But when this is working fine against oracle 7.3.4.Any suggestion ?

Thanks. Pands
