You can't get unicode even via **params. Encoded strings work okay,
though. I.e.:
# doesn't work:
dict(**{u'\u1000': 'foo'})
# even this doesn't work:
dict(**{u'foo': 'foo'})
# This does work:
dict(**{u'\u1000'.encode('utf8'): 'foo'})
However, I thought WebOb wouldn't give you unicode keys by default. You
need to set decode_params_names = True on the request to get that.

If you use request.params.mixed() to get the keyword arguments, you'll
get lists in these cases. Some people find that frustrating, as things
may be lists or not (e.g., one checkbox checked is not a list, two are),
or misformed submissions cause TypeErrors and whatnot when you
unexpectedly get multiple values. Anyway, that's the justification
(along with ordering and some other things) for not using a plain dict
as the form representation.
