确切来说不是mysql的问题，只是我在使用xampp中的Mysql(实际上是mariadb)时，碰到了这个问题。
导入sql文件
如上，无法识别中文路径。那四个打问号的字符本应该是“必知必会”。
为什么？
如下，可能和cmd中的编码有关系。

wikipedia中解释了
Code page 437 is the character set of the original IBM PC (personal computer). It is also known as CP437, OEM-US, OEM 437,[1] PC-8,[2] or DOS Latin US.[3] The set includes ASCII codes 32–126, extended codes for accented letters (diacritics), some Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII"[2] (one of many mutually incompatible ASCII extensions).
我需要将这里改成utf-8。cmd才能识别输入的中文。
