OK.

Yes, I think it is the DM. I just tried using the Ansi ODBC Test program
with the SQL Server driver. It called the Unicode functions as well...

The difference with SQL Server is that it has separate types for
unicode/non-unicode data (nvarchar/varchar) which can be mixed in the
same table. I don't fully understand what the possible side effects
might be yet, but what if we only set conn->unicode if the connection is
made to a unicode database AND the driver tries to call SQL*ConnectW?

Comments anyone?

7.2.x uses the 6.4 protocol. That's normal :-)
