Note that apparently simple tests can be fraught. There is a bug against
ks.isPlainKey. It ends with:
if s in string.printable:
return True
if len(s) > 1:
return False
return unicodedata.category(s).startswith('C')
Why this fails is mysterious. Perhaps the test should be:
return unicodedata.category(s).startswith('C') if len(s) == 1 else False
But I rather doubt that this will work. Or maybe the test against 'C' is
the culprit.
In any event, these kinds of unicode tests are trickier than I hoped.
