But that has nothing to do with character sets. The same principle could be used for any array of ints.

Python does, in fact, store integers in different-sized blocks of
memory according to size - though not for anything smaller than
32-bit.

>>> sys.getsizeof(100)
14
>>> sys.getsizeof(1000000000000000000000000000000000)
28

So why this is suddenly a bad thing for characters is a mystery none
but he can comprehend.
