Small illustration. Take an a4 page containing 50 lines of 80 ascii
characters, add a single 'EM DASH' or an 'BULLET' (code points> 0x2000),
and you will see all the optimization efforts destroyed.
sys.getsizeof('a' * 80 * 50)
4025
sys.getsizeof('a' * 80 * 50 + '•')
8040
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
