Isn't this overrated?
First, if you have a Python version that has the wrong version, just print out
its sys.maxunicode and choose the right version according to that (if
sys.maxunicode == 65535, you need to compile an UCS-4 version, otherwise an
Second, once you have encountered this issue, you know what you need the
subsequent times. There are only two possibilities after all.
