Some SHOW VARIABLES have been renamed:

collation_client  -> character_set_client
collation_results -> character_set_results
character_set     -> character_set_server

SET NAMES now doesn't start client->server conversion
SET CHARACTER SET now starts both client->server and server->client conversion
