Unicode is actually called Unicode.

http://www.unicode.org/

The Python 2.x *type* "unicode" was renamed to "str" in Py3.

Ah, right. That wasn't updated. Thanks for bringing it up. It should read
encoding="unicode".

If I were to read encoding="str" somewhere, I'd be puzzled what it might
mean. Even encoding="unicode" isn't ideal, because Unicode is not an
encoding. But practicality beats purity here, and it's certainly more
obvious than encoding="str".
