Yes.

Compare to:

>>> sys.getsizeof('a\u0100')
42

The reason for the difference you posted is that pure ASCII strings
have a further optimization, which I glossed over and which is purely
a savings in overhead:

>>> sys.getsizeof('abcde') - sys.getsizeof('a')
4
>>> sys.getsizeof('ábçdê') - sys.getsizeof('á')
4
