    UTF8 text files might include a BOM character. You can test it by using a decent text editor such as Notepad++.

    Always prefer to work with text files encoded with UTF8 without BOM.

    This code reads a UTF8 text file and removes the BOM character if needed:
    Sub ReadUTF8FileMaybeWithBOM (Dir As String, Name As StringAs String
    Dim s As String = File.ReadString(Dir, Name)
    If s.StartsWith(Chr(0xFEFF)) Then
           s = s.SubString(
    End If
    Return s
    End Sub
