Please post here part of your hibernate.cfg.xml where the connection is
configured (or if you get it from JNDI, configuration of your JNDI
DataSource).

Most likely you should add ?encoding=UTF8 after the DB name to have
something like this:

jdbc:firebirdsql:localhost/3050:/path/to/mydb.fdb?encoding=UTF8

By default the NONE character set is used, then Jaybird tries to convert
it to byte[] using the systems's default charset.
