Well, we're talking about Python 3 here right? In which case the above 
involves only unicode, so why do we need to guess anything? Just use 
utf-8 and be done with it...

Indeed, surely this happens when you have bytes and need to do something 
with it? That's not what my example above is about...

>>> Where you care about what encoding is used:
>>>
>>> Message['Subject']=Header('Some text',encoding='utf-8')

...it's covered by this.

>>> If you have bytes, for whatever reason:
>>>
>>> Message['Subject']=b'some bytes'.decode('utf-8')
>>>
>>> ...because only you know what encoding those bytes use!

>> So you're saying that __setitem__() should not accept raw bytes?

Indeed :-)
