anyone can help where goes wrong?

The code you show deals with reading the value from a file, but the exception seems to come from trying to insert it into the database. I'm guessing the problem is the column in the database is defined to contain a single character, but only understands single byte (ASCII) characters. Is it possible to configure your database to support Unicode? Otherwise, you will probably have to break the Unicode into two bytes and store it that way, or convert it back to UTF and store it as between one and three bytes.

thansk greg, appreciated that.
