[[Bug] skip-character-set-client-handshake]


	<I'm using MariaDB with my gameservers. Server works with db through sourcemod.
In my db i'am using utf8 encoding, and all works fine on MariaDB 5.3.8 with params:
init-connect = "SET NAMES 'utf8' COLLATE 'utf8_general_ci'"
But after upgrade to 5.5.27 i found a 'bug'.
When i'm send query from my game server, over time character_set_connection, character_set_client and character_set_results set to latin1.
After enable log i saw:
                   88 Connect   login@domain as anonymous on sourcebans
                   88 Query     SET NAMES 'utf8' COLLATE 'utf8_general_ci'
                   88 Query     SET NAMES latin1
                   88 Query     SHOW VARIABLES LIKE '%character_set%'
But my request is only show vars.
I assumed that sourcemod is guilty. But skip-character-set-client-handshake is set! I disable it, and try again.
At this time i send SET collation_connection = utf8_general_ci and SET NAMES utf8 after my query. But over time it set to latin1 again.
No errosr in error.log
Sorry for my english.>
	<I don't know how to repeat it manually (without sourcemod app)>
	<It works fine in previous versions. Just not accept NAMES from client.>
