You should convert your database to an appropriate encoding for the data
it contains (perhaps LATIN1?). If the database encoding is SQL_ASCII,
the JDBC driver has no way of knowing how to convert bytes >127 to
Java's UTF-16 String representation.
Basically, SQL_ASCII is only going to work with the JDBC driver if you
only store 7-bit ASCII, or if you happen to be very lucky and have all
clients everywhere use a client_encoding of UNICODE.
