docs: multibyte collation for HandshakeResponse41

[dveeden]

import mysql.connector c = mysql.connector.connect( host='127.0.0.1', port=3306, user="test", password="test", collation="utf8mb4_ja_0900_as_cs", ssl_disabled=True ) cur = c.cursor() cur.execute("SHOW SESSION VARIABLES LIKE '%collation%'"); for col in cur: print(col) cur.close() c.close()

Output:

('collation_connection', 'utf8mb4_ja_0900_as_cs') ('collation_database', 'utf8mb4_0900_ai_ci') ('collation_server', 'utf8mb4_ja_0900_as_cs') ('default_collation_for_utf8mb4', 'utf8mb4_0900_ai_ci') 

This uses the utf8mb4_ja_0900_as_cs collation, which has ID=303. And 303 in hex is 0x012f. If only the lower 8 bits are sent this would be 0x2f (47 decimal). However the 0x01 is actually sent in the next byte.
