-.. dialect:: mysql+zxjdbc
-    :name: zxjdbc for Jython
-    :dbapi: zxjdbc
-    :connectstring: mysql+zxjdbc://<user>:<password>@<hostname>[:<port>]/<database>
-    :driverurl: http://dev.mysql.com/downloads/connector/j/

-    .. note:: Jython is not supported by current versions of SQLAlchemy.  The

-
-Character Sets
---------------
-
-SQLAlchemy zxjdbc dialects pass unicode straight through to the
-zxjdbc/JDBC layer. To allow multiple character sets to be sent from the
-MySQL Connector/J JDBC driver, by default SQLAlchemy sets its
-``characterEncoding`` connection property to ``UTF-8``. It may be
-overridden via a ``create_engine`` URL parameter.
