Small illustration. Take an a4 page containing 50 lines of 80 ascii

sys.getsizeof('a' * 80 * 50)

sys.getsizeof('a' * 80 * 50 + '•')

This example is still benefiting from shrinking the number of bytes
in half over using 32 bits per character as was the case with Python 3.2:
>>> sys.getsizeof('a' * 80 * 50)
16032
>>> sys.getsizeof('a' * 80 * 50 + '•')
16036

Perhaps the solution should've been to just switch between 2/4 bytes
instead
of 1/2/4 bytes. :-)
