VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

' Note: Requires Chilkat v9.5.0.83 or greater.

' This requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.
