Thanks a lot, the end of mystery. So I will probably stay with my
subclassing dict:

class NoteDict(dict):
    def __init__(self):

    def __getitem__(self,y):
        key = unicode(y)
        return dict.__getitem__(self,key)

    def __setitem__(self,i,y):
        key = unicode(i)

    def __delitem__(self,y):
        key = unicode(y)

Is there any better way how to do it?
