   Looks like a byte order mark. I think notepad has a tendency to add these? For a workaround, you might try copy/pasting to a new file in another editor and saving that. For a potential change in this library, we could use encodings.utf_8_sig to open the file. That would be useful in this case. More generally, it would be nice if there is a way to open the file "like Python opens the file". That would cover coding: comments, but I don't know how that is done or if it is available to us at all.

   I think that it is triggered by your situation. I don't think that makes it "your fault". I also don't think that means there isn't anything to fix in this project. I think we should make a change to allow for BOMs, and anything else Python allows such as the coding comments. I just haven't made the time to do that.
