> The FSR simply stores a Unicode string as an array[*] of ints (the Unicod=
e code points of the characters of the string. That's it. Then it uses a me=
mory-efficient way to store this array of ints. 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.
