[New-bugs-announce] [issue36671] str.lower() looses character information when working with UTF-8

[Kadam Parikh]

New submission from Kadam Parikh <parikhkadam at gmail.com>:

When converting a particular UTF-8 character "İ" to lowercase, it doesn't behave correctly. It returns two lowercase characters instead of one. This is not as desired.

Code:

>>> print("\u0130")
İ
>>> print("\u0130".lower())
i̇
>>>
