Neither character above is larger than 4 bytes. You forgot to deduct the
size of the object header. Python is a high-level object-oriented
language, if you care about minimizing every possible byte, you should
use a low-level language like C. Then you can give every character 21
bits, and be happy that you don't waste even one bit.
