Grapheme clusters, a.k.a.real characters

[Steve D'Aprano]

>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
