Using ISO-8859 with Card and Mac's

Hello!
Were having trouble with our Macs
using Oracle Card. The Suns and PC
in our net uses ISO-8859 character
set but the macs wont use it.
My question is is there a way to
get Oracle card for mac to work in ISO-8859 character set rather than in Apples
own character set ?
Please answer quickly.
Were currently using version 6.0
of Oracle database server.
The version of Card were using is 1.1.2. Plaese answer by mail!

Thank's
