Describe the bug
The script has only been tested on macOS and I suspect on Windows/Linux the -p and -n options are removing the whole "home" IDE folder for the user. I don't have either system to test on, so this requires someone to help out.

一、修改MySQL的配置文件

MySQL的配置文件 my.cnf ，所在位置一般在：/etc/my.cnf，如果不在这个目录下，可以搜索下：whereis my.cnf

修改每个对应项为 utf8mb4 编码：

[client]
default-character-set=utf8mb4
 
[mysql]
default-character-set=utf8mb4
 
[mysqld]
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

character-set-client-handshake = false

修改完成后，重启MySQL，然后查看配置
