please verify datasource configuration in production environment whether attributes - useunicode , characterencoding set properly.
example:

<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/exodb?relaxautocommit=true&amp;amp;autoreconnect=true&amp;amp;useunicode=true&amp;amp;characterencoding=utf8"/>
