It sounds like you're not calling the "encode" method correctly. But
it's hard to say when you didn't include that bit of code. You may
need to check your database's docs to make sure it accepts unicode
strings and if so, what types (utf-8, 16, 32).

See this post for a similar problem:

and this link details tuple usage: http://www.faqs.org/docs/diveintopython/odbchelper_tuple.html
