this looks like that unicode version 14 has some new things

We don't update the unicodedata database in patch releases because updates are
backwards incompatible. Python 3.9 will ship with 13.0. Python 3.10 is going to
ship with 14.0.

Thank you for the pointer!

Thank for the (re) explanation. Unicode is tough!
Basically this is the issue i have really in the end with the folding: what
used to be a proper alpha string is not longer one after a lower() because the
second codepoint is a punctuation and I use a

PS: The first entry of the result is a decomposed string, too:
>>> r = [x.lower() for x in 'İ']
>>> hex(ord(r[0][0]))
'0x69'
>>> hex(ord(r[0][1]))
'0x307'

It's not. Read again my previous comment.

There is a weird thing though (using Python 3.6.8):
>>> [x.lower() for x in 'İ']
['i̇']
>>> [x for x in 'İ'.lower()]
['i', '̇']
I would expect that the results would be the same in both cases. (And this is a
source of a bug for some code of mine)
STINNER Victor added the comment:
> Should it not simply return “i”?
Python implements the Unicode standard.
>>> "U+%04x" % ord("İ")
'U+0130'
>>> ["U+%04x" % ord(ch) for ch in "İ".lower()]
['U+0069', 'U+0307']
>>> unicodedata.name("İ")
'LATIN CAPITAL LETTER I WITH DOT ABOVE'

New submission from Dogan :
Hey there,
I believe I've come across a bug. It occurs when you try to lower() the Turkish
uppercase letter "İ". Gonna explain it with example code since it's easier:
>>> len("Ş")
1
>>> len("Ş".lower())
1
>>> len("Ğ")
1
>>> len("Ğ".lower())
1
>>> len("Ö")
1
>>>
