I experienced this problem with java and mysql on eclipse the solution was From eclipse click right on your project and choose properties and choose utf-8 like this photo

Then from the database chose base encoding and utf-8 tables.

Finally, all database queries must be utf-8 encoded like this

String url = "jdbc:mysql://host/database?useUnicode=true&characterEncoding=utf8";
