New submission from Dogan <[email protected]>:
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
>>> len("Ö".lower())
1
>>> len("Ç")
1
>>> len("Ç".lower())
1
>>> len("İ")
1
>>> len("İ".lower())
2
When you lower() the Turkish uppercase letter “İ”, it returns a 2 chars long
string with the first character being “i”, and the second being chr(775).
Should it not simply return “i”?
