打开CMD.exe命令行窗口,通过 chcp命令改变代码页
UTF-8的代码页为65001,ANSI/OEM - 简体中文 GBK为936,window default OEM - 美国为437
如果chcp命令得到437，那么一定不能显示中文，此时的中文为???.如果是乱码，那么一定字符码不是UTF-8

使用chcp 936在CMD.exe命令行窗口。
也可以该注册表，在开始运行里输入regedit 找到分支 HKEY_CURRENT_USER/Console/%SystemRoot%_system32_cmd.exe，再双击右边CodePage选项将数值改为十六进制3a8或十进制"936
十六进制"000003a8"或十进制"936"，表示“936 (ANSI/OEM - 简体中文 GBK)”。
十六进制"000001b5"或十进制"437"，表示“437 (OEM - 美国)”。
