"Full support" for Unicode is almost never what you want unless your program literally interacts with font rendering, and then it's not even close to enough. Most of the time the important requirement is that you don't mangle data as it passes through your program, which e.g. early py3 spectacularly failed and is still not better at than py2 in the very common case where your input is not actually necessarily well-formed Unicode, but just an unrestricted byte array that by convention usually contains utf-8. Most of what people hope for Unicode support to achieve beyond that (case-folding, homoglyph elimination, &c.) is not only not achieved, but not even possible.
