Actually it does; it covers all of the Unicode range, by using
(effectively) UTF-16. Characters that cannot be represented in one
16-bit number are represented in two. That's not "just" covering a
different range. It's being buggy. And it's creating a way for code to
unexpectedly behave fundamentally differently on Windows and Linux
(since the most common builds for Windows were narrow and for Linux
were wide). This is a Bad Thing for Python.
