I see that you're using Microsoft Windows.
Microsoft likes to indicate that a text file contains UTF-8 by starting
the text with u"\xFEFF" encoded as UTF-8. You're opening the file with
the encoding "utf-8", so you're seeing that marker.
Try opening the file with the encoding "utf-8-sig". That will drop the
marker if it's present.
