Unicode problem with Microsoft Access

Hi,

Sorry to ask a question which was probably raised before but the search
on the archive is not working.

I am trying to save data from Access 2000 (tryed both XP and W2K) into a
7.4.2 database using the pgsql-odbc 07-03-0200 driver. This used to work
previously with Latin1 encoding but we had to switch to UNICODE encoding
in the database and I now get:

Error: Invalid Byte sequence for encoding “UNICODE”: 0xe36f (#7)

I tryed to switch to the Unicode (Beta) driver but I get:

ODBC—Call Failed
Specified Driver could not be loaded due to system error 126 (PostgreSQL
Unicode (Beta)). (#160)

Is there any easy way to fix that problem?

Thanks,
Benoit
