Just to stick with this funny character ẞ, a ucs-2 char
in the Flexible String Representation nomenclature.

It seems to me that, when one needs more than ten bytes
to encode it, 

>>> sys.getsizeof('a')
26
>>> sys.getsizeof('ẞ')
40

this is far away from the perfection.

BTW, for a modern language, is not ucs2 considered
as obsolete since many, many years?
