I am using JDBC to connect to a Sybase table that contains extended ascii characters (ascii code >= 128).
And they are returned as ?.
I am calling this from Dot Net for Apache Spark using JConn4. The sybase database is using iso_1.
In another test I was able to make ODBC show the character correctly by instructing ODBC to not use character conversion.
How could I make jdbc read the extended ascii characters properly?
