Python delightful? In Python 2, the behavior of Unicode strings (UTF-16 vs. UTF-32) depends on what options the interpreter was compiled with. Then they made a backward-incompatible change to "fix" Unicode but did the exact wrong thing (UTF-32, UCS-2 or ISO-8859-1 depending on string content) instead of the right thing (UTF-8 storage with UTF-32 iterators).
I got the impression that the internal encoding Python chooses for a string is an implementation detail you shouldn't (and cannot) care about. All the public ways if accessing string contents operate on code points, unless you convert the string to a byte array first.
