It's easy to save file (with FSO) using UNICODE encoding (-1), ISO or serveur setting.

Hi just have to tell

' Unicode exemple
Set oFichier = oFSO.OpenTextFile(path,2,true,-1)

But how do you save that faile using UTF-8 encoding?

I dont have any problems with XML document (Msxml2.DOMDocument.4.0) with use of MS CodePage and charset :

<%@ CodePage=65001 Language="VBScript"%>
<%Response.CharSet = "utf-8"%>

And of course the header :
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

But with FSO I never get UTF-8 File!!
