首先想要了解MySQL的字符集，就需要去官方文档看看字符集是如何介绍的。英语不错的话，看官方文档应该是没问题。在搜索框里搜一下就可以找到相关的解释。我就在这里整理一下，以便后期查看。字符集在官方文档下面这一章节：
Chapter 10 Character Sets, Collations, Unicode

一、字符集设置
MySQL数据库可以做到：
1、使用多种字符集存储字符串。
2、使用多种排序规则比较字符串。
3、在同一服务器、同一数据库、甚至同一表中混合具有不同字符集或排序规则的字符串。
4、在任何级别启用字符集和排序规则的规范。
MySQL可以设置如下40种字符：

String expressions have a repertoire attribute, which can have two values:
-
ASCII: The expression can contain only characters in the Unicode range U+0000 to U+007F.
-
UNICODE: The expression can contain characters in the Unicode range U+0000 to U+10FFFF. This includes characters in the Basic Multilingual Plane (BMP) range (U+0000 to U+FFFF) and supplementary characters outside the BMP range (U+10000 to U+10FFFF).
