vbs实现unicode和ascii编码转换
一、Copy a Unicode File to an ANSI File
WiToAnsi.vbs文件：
' Utility to rewrite a Unicode text file as an ANSI text file

Option Explicit

Const ForAppending = 8
Dim argCount:argCount = Wscript.Arguments.Count
If argCount > 0 Then If InStr(1, Wscript.Arguments(0), "?", vbTextCompare) > 0 Then argCount = 0
If (argCount = 0) Then
Wscript.Echo "Utility to copy Unicode text file to an ANSI text file." &_
vbNewLine & "The 1st argument is the Unicode text file to read" &_
vbNewLine & "The 2nd argument is the ANSI text file to write" &_
vbNewLine & "If the 2nd argument is omitted, the Unicode file will be replaced"
Wscript.Quit 1
End If
Dim inFile, outFile, inStream, outStream, inLine, FileSys, WshShell
If argCount > 1 Then
outFile = Wscript.Arguments(1)
inFile = Wscript.Arguments(0)
Else
outFile = Wscript.Arguments(0)
inFile = outFile & ".tmp"
Set WshShell = Wscript.CreateObject("Wscript.Shell")

End If
