OK. Changed as you suggested.

I'm also scan with fresh eye over my tests and catch error in test with
cpUNKNOWN. Because during lookup encoding name translated to canonical
form (i.e. to lowercase, and '-' replaced with '_' or even removed), I
catch  incompleteness in self.make_wrapped_streams(). New version of my
patch is attached. I think it's final version.

I see that sometimes it useful to re-use a fake encoding, sometimes is
not. I prefer to leave things in current state, because now we have
correct tests.
