打開CMD.exe命令行窗口,通過 chcp命令改變代碼頁
UTF-8的代碼頁為65001,ANSI/OEM - 簡體中文 GBK為936,window default OEM - 美國為437
如果chcp命令得到437，那么一定不能顯示中文，此時的中文為???.如果是亂碼，那么一定字符碼不是UTF-8

使用chcp 936在CMD.exe命令行窗口。
也可以該注冊表，在開始運行里輸入regedit 找到分支 HKEY_CURRENT_USER/Console/%SystemRoot%_system32_cmd.exe，再雙擊右邊CodePage選項將數值改為十六進制3a8或十進制"936
十六進制"000003a8"或十進制"936"，表示“936 (ANSI/OEM - 簡體中文 GBK)”。
十六進制"000001b5"或十進制"437"，表示“437 (OEM - 美國)”。
