Interest Ask. I did some searches, and it looks like you can find all the options available here: https://docs.python.org/3/library/codecs.html#standard-encodings

therefore, in this case, not one! It should be utf_16. However, with my experience with python, I would not be surprised if they will sanitize the argument you provided so that it works independently. And from the link, it looks like they are doing! therefore utf-16must be a valid alias.
