Maybe this will work.

VBScript uploads a file using FrontPage RPC:  file name should consist of ASCII characters only

Function StringToByteArray(str)
   Set stream = CreateObject("ADODB.Stream")
   stream.Open
   stream.Type = 2 ''adTypeText
   stream.Charset = "ascii"
   stream.WriteText str
   stream.Position = 0
   stream.Type = 1 ''adTypeBinary
   StringToByteArray = stream.Read()
   stream.Close
End Function

Sub UploadFile(sourcePath, siteUrl, docName, title, checkincomment, userName, password)

   strHeader = "method=put+document%3a12.0.4518.1016" + _
      "&service_name=%2f" + _
      "&document=[document_name=" + Escape(docName) + _
      ";meta_info=[vti_title%3bSW%7c" + Escape(title) + "]]" + _
      "&put_option=overwrite,createdir,migrationsemantics" + _
      "&comment=" + _
      "&keep%5fchecked%5fout=false" + vbLf
   bytearray = StringToByteArray(strHeader)

   Set stream = CreateObject("ADODB.Stream")
   stream.Open
   stream.Type = 1 ''adTypeBinary
   stream.Write byteArray

   Set stream2 = CreateObject("ADODB.Stream")
   stream2.Open
   stream2.Type = 1 ''adTypeBinary
   stream2.LoadFromFile sourcePath
   stream2.CopyTo stream, -1
   stream.Position = 0

   Set xmlHttp = CreateObject("MSXML2.XMLHTTP")

   xmlhttp.setRequestHeader "User-Agent", "FrontPage"
   xmlHttp.send stream

   If xmlHttp.status = 200 Then

       If Instr(xmlHttp.responseText, "successfully") = 0 Then

          MsgBox "ERROR: " & vbCrLf & xmlHttp.responseText

          xmlhttp.setRequestHeader "User-Agent", "FrontPage"
          xmlHttp.send strHeader



       End If

   End If

   If xmlHttp.status / 100 <> 2 Then
      MsgBox "ERROR: status = " & xmlHttp.status & vbCrLf & xmlHttp.responseText
   End If

End Sub
