I know that we have to use `setattr` method when we are outside of an object. However, I have troubles calling `setattr` with unicode key leading me to use `__setattr__` directly.

 class MyObject(object):
 def __init__(self):
 self.__dict__["properties"] = dict()
 def __setattr__(self, k, v):
 self.properties[k] = v
 obj = MyObject()

And I get the following content of `obj.properties`:

 - `setattr(obj, u"é", u"à")`: raise UnicodeEncodeError
 - `setattr(obj, "é", u"à")`: `{'\xc3\xa9': u'\xe0'}`
 - `obj.__setattr__(u"é", u"à")`: `{u'\xe9': u'\xe0'}`

I don't understand why Python is behaving with these differences
