代碼如下
復制粘貼，保存為bat，把需要轉換的文檔拖動到這個bat上面打開
ANSI轉UTF-8 直接用
UTF-8轉ANSI 將下方標紅的數字調換位置即可
::注釋
::code1=ANSI(GB2312)
::code2=Big5
::code3=Shift_JIS
::code4=EUC-KR
::code5=UTF-8
::code6=Unicode
@echo off & setlocal enabledelayedexpansion
::設置文件轉換前編碼類型，請參考上面編碼序號，序號5即指code5也就是UTF-8編碼
set aaa=1
::設置文件轉換后編碼類型，請參考上面編碼序號，序號1即指code1也就是ANSI(GB2312)編碼
set bbb=5
::設置要轉換的文件名
set file=%~nx1
set wfiles=%file%
::開始轉換

del MakeBOM.vbs
del Unicode.BOM
move /y "%codepth%\%file%" "%file%"
rd /s /q "%codepth%"
pause
效果：
用 文本文檔-另存為 可以查看和改變文檔的編碼
可見文件的編碼已經轉換成功
