In the best of all possible worlds the Related list would contain a reference to this question which I found as the first hit for “vbscript adodb.stream bom vbscript site:stackoverflow.com”.
Based on the second strategy from boost’s answer:
Option Explicit
Const adSaveCreateNotExist = 1
Const adSaveCreateOverWrite = 2
Const adTypeBinary = 1
Const adTypeText = 2
Dim objStreamUTF8 : Set objStreamUTF8 = CreateObject("ADODB.Stream")
Dim objStreamUTF8NoBOM : Set objStreamUTF8NoBOM = CreateObject("ADODB.Stream")
With objStreamUTF8
.Charset = "UTF-8"
.Open
.WriteText "aÄö"
.Position = 0
.SaveToFile "toto.php", adSaveCreateOverWrite
.Type = adTypeText
.Position = 3
End With
With objStreamUTF8NoBOM
.Type = adTypeBinary
.Open
objStreamUTF8.CopyTo objStreamUTF8NoBOM
.SaveToFile "toto-nobom.php", adSaveCreateOverWrite
End With
objStreamUTF8.Close
objStreamUTF8NoBOM.Close
