New submission from Frank Feuerbacher <frank at feuerbacher.us>:
This blasted Turkish I will be the death of us all...
https://www.unicode.org/versions/Unicode14.0.0/ch05.pdf has a lovely graphic on page 238 of the behavior of upper/lower casing of the various I's and when locale is Turkish or not. It seems that Python 3.9.5 is broken, and I see no evidence that version 10 has fixed it.
Basically, U-0049 (I) should lower case to U-131 (ı) and vice-versa, when locale is tr_TR. The rules are different for other locales.
