Creating a stored procedure: setting the character set and collation

When creating a MySQL stored procedure how does one set the character set and collation? The MySQL documentation does not provide any examples and to the general syntax is slightly unclear.

mysql> show procedure status\G

*************************** 1. row ***************************
                  Db: MslLandingSequence
                Name: DeploySkycrane
                Type: PROCEDURE
             Definer: curiosity@localhost
            Modified: 2012-08-04 00:05:16
             Created: 2011-11-12 00:02:45
       Security_type: DEFINER
             Comment: 
character_set_client: latin1
collation_connection: latin1_swedish_ci
  Database Collation: latin1_swedish_ci

The last three items should be Unicode. Thanks.
