>From time to time, people discover that Python's string algorithms work on code
points rather than "real characters", which can lead to anomalies like the
following:
s = 'xäex'
s = unicodedata.normalize('NFD', s)
print(s)
print(s[::-1])
which results in:
xäex
xëax
If you're interested in this issue, there's an issue on the bug tracker about
it, which is seeing some activity.
