OB默认字符集不是utf8mb4吗，我看文档上这几个参数默认值也是utf8mb4,怎么全局修改啊？
我使用SET global character_set_client = utf8mb4;
SET global character_set_results = utf8mb4;
SET global character_set_connection = utf8mb4;
set session character_set_client=‘utf8mb4’ ;
set session character_set_connection =‘utf8mb4’;
set session character_set_results =‘utf8mb4’;都不行，重新连接就恢复了。
