A string of characters. Each character in the string is a 32-bit Unicode
character. The internal UTF-16 encoding is hidden from clients.
A string is a Category of its Characters, and of its substrings:
Clean. Far, far away from a unicode handling which may require
18 bytes (!) more to encode a non ascii n-chars string than a
ascii n-chars string.
(With performances following expectedly "globally" the same logic)
sys.getsizeof('a')
26
sys.getsizeof('\U0001d11e')
44
jmf
In [3]: sys.getsizeof(1)
Out[3]: 14
What a disaster, 13 bytes wasted storing 1. I'll just rush off to the
bug tracker and raise an issue to get the entire Cpython core rewritten
before Armaggeddon strikes.
