internal charset to one associated with currently being handled query. To note such a query can come from interactive client either. There was a discussion within replication team and Monty who's suggestion won. It avoids straightforward parsing of all `set' queries that could affect client side character set. According to the idea, mysql client does not parse `set' queries but rather cares of `charset new_cs_name' command. This command is generated by mysqlbinlog in form of exclaiming comment (Lars' suggestion) so that enlightened clients like `mysql' knows what to do with it. Interactive human can switch between many multi-byte charsets during the session providing the command explicitly. To note that setting new internal mysql's charset does not trigger sending any `SET' sql statement to the server.
