yup, as far as I know, you should use setByte(), and preapred statment.
usually when you read from and write to database, there is a implicit Type exchange, for chinese word, the encode is GB23121(for example), but english is iso-8859-1(for example),

sometime you need use String.encode() to get correct answer. have a fun!
