Description: Problems with ODBC
Details:

I installed PostgreSQL and ODBC driver on my computer under Windows 2000 and
used MS Access as a client program.
I created tables with varchar(50) primary key, and accessed them with MS
Access creating linking tables.
There was no problem, if I inserted latin letters or digits into a primary
key of a MS Access linking table.
But I'm ukrainian and tried to insert ukrainian letters into the primary key
via ODBC. I received a strange message from ODBC that some wrong characters
encountered.
In pgAdminIII I saw that my records were successfully inserted (even with
cyrillic letters in primary key).
I suppose that there are some bugs in ODBC driver, especially in cyrillic
letters processing in primary keys.
