How to specify connection properties?

[marhop]

Description: It is not clear from the documentation how connection properties like e.g. characterEncoding=UTF-8 (MySQL) should be configured. I guess it could be done using the generic jdbc import module and specifying a MySQL connection string like jdbc:mysql://localhost:3306?characterEncoding=UTF-8, but I would prefer to use the mysql module. Is this possible?
