But this isn't relevant to Python's str, because Python's str never uses UTF-8.

Really? I thought in python 3, strings are all unicode... so what encoding do they use, then?

No encoding is used. The actual code points are stored as integers of the same size. If all code points are less than 256, they are stored as 8-bit integers (bytes). If some code points are greater or equal to 256 but less than 65536, they are stored as 16-bit integers and so on.
