---数据库字符集

服务器本身的的这个属性：
show variables like ‘collation_%‘;
show variables like ‘character_set_%‘;
方法一：show variables like ‘%character%‘;
方法二：show variables like ‘collation%‘;

查看支持的字符集：
show charset;

show table status from class_7 like ‘test_info‘;
 show table status from myblog like ‘wp_posts‘;   #特定表
 show table status from myblog ;  　＃全部表


我大概看了一下子我wordpress 库表，　放心了！　
utf8mb4_unicode_ci

设置字符集：

alter database 库名 default character set 字符集;
