I'm using nvarchar2 columns in an Oracle 9.2i table. From a single connection in a single program I write data to the column and then read it back. I get different characters than I sent in. Can anyone offer any suggestions?

Jonathan Gennick writes that Oracle translates Unicode data to/from the national character set. Is there a way to turn this off? It's probably my problem.

Specifics: I'm using Visual Basic 6.0 on Windows 2000 (both of which natively use a UCS-16/UTF-16 character set) and MDAC/ADO 2.8. I insert data without bind variables: INSERT ... VALUES(N'~') where the ~ can be any UTF-16 character. For almost all code points above x007F the value is different when I read the column back in a record set.

Thanks, Jim
