Support non UTF-8 strings

[yvz5]

The database has german characters in it "üÜäÄöÖ".

this is how I try to get the data:
cursor.get_data::<String>(3)

is this a bug or should I use some other data type ?

Looks like a bug. Could you please share additional details on RDBMS and ODBC driver used?

I have SQL Anywhere 17 both 32-bit and 64-bit ODBC Drivers installed. When I try the same connection string and sql statement in c#, everything is fine.

String is a UTF8 encoded string. The data returned does not seem to be UTF8 encoded. If we had support for Vec<u8> right now, I would suggest using that and do the encoding yourself. We could also think about retrieving String as wide characters.
