[issue12737] str.title() is overzealous by upcasing combining marks inappropriately

[Irit Katriel]

Irit Katriel <iritkatriel at yahoo.com> added the comment:

Of the examples given two seem ok now, but the Istanbul one is still wrong:

>>> "déme un café".title()
'Déme Un Café'
>>> "ᾲ στο διάολο".title()
'Ὰͅ Στο Διάολο'
>>>

>>> "i̇stanbul".title()
'İStanbul'
