Openning an Oracle Database with Doctrine and Symfony doesn't support by default utf8 charset.

To support it, it is necessary to specify charset=AL32UTF8 in the dsn of the database in config/databases.yml. Analogous to the example shown at
http://groups.google.com/group/doctrine-user/browse_thread/thread/d0d22145d8bdc83
however we have been able to use it fully only with the oracle driver (instead of oci), for example:

oracle:dbname=//192.168.2.9:1521/nomina_dev;charset=AL32UTF8
