简单来说 CHCP 命令用来设置 DOS 窗口的编码,DOS 默认代码为 936 简体中文 GBK。
C:\Users\Administrator> chcp /? 显示或设置活动代码页编号。 CHCP [nnn] nnn 指定代码页编号。 不带参数键入 CHCP 以显示活动代码页编号。
(1)查看默认代码页数
C:\Users\Administrator> chcp 活动代码页: 936
如下图:

(2)将代码页设置为 65001,即 UTF-8,例如:
C:\Users\Administrator> chcp 65001 回车后显示如下信息: Active code page: 65001 C:\Users\Administrator>
如下图:
