mysql --database=dbname -B -N -e "SHOW TABLES" | awk '{print "ALTER TABLE", $1, "CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;"}' | mysql --database=dbname &
This loops through all tables and changes their collations to UTF8. You should backup beforehand though in case some data is lost in the process.
