(Xojo Plugin) Convert a File's Character Encoding from UTF-8 to UFT-8-BOM

To add a utf-8 BOM to a file is just a matter of prepending these 3 bytes to the file: 0xEF 0xBB 0xBF.

This may be difficult in some programming languages, or it may be trivial in either. Therefore, the Chilkat solution you see here might be helpful, or in a language such as C++, the Chilkat solution isn't really necessary because it's easy to do yourself.

Dim charset As New Chilkat.Charset

charset.FromCharset = "utf-8"
charset.ToCharset = "bom-utf-8"

Dim success As Boolean
success = charset.ConvertFile("qa_data/txt/helloWorld.txt","qa_output/helloWorldBom.txt")
If (success <> True) Then
    System.DebugLog(charset.LastErrorText)
    Return
End If

System.DebugLog("Success.")
