3.3, Python does away with the difference between "narrow builds" (which
save memory at the expense of correctness) and "wide builds" (which give
correct Unicode behaviour at the cost of memory). Instead, Python 3.3 now
has optimized strings that use only as much memory as needed. Pure ASCII
strings will use 1 byte per character, while Unicode strings use 1, 2 or
4 bytes per character as needed. And it all happens transparently.
[topic beeing more of less closed]
Your paragraph is mixing different concepts.
When it comes to save memory, utf-8 is the choice. It
beats largely the FSR on the side of memory and on
the side of performances.
How and why? I suggest, you have a deeper understanding
of unicode.
May I recall, it is one of the coding scheme endorsed
by "Unicode.org" and it is intensively used. This is not
by chance.
