[issue34723] lower() on Turkish letter "İ" returns a 2-chars-long string

[Philippe Ombredanne]

Philippe Ombredanne <pombredanne at nexb.com> added the 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)
