When one has to face such a characteristic sequence,
the first thing to do is to think "utf-8".
(Not a proof)
>>> a = list(range(0x0410, 0x0415))
>>> a += list(range(0x0440, 0x0445))
>>> a += list(range(0x0480, 0x0485))
>>> import unicodedata as ud
>>> for i in a:
... hex(i), chr(i).encode('utf-8'), ud.name(chr(i))
...
