How about throwing NotImplementedError if [encoding] is not UTF-8?

I suspect most of the time when encodings get set to something other than the
default, they're coming from some external configuration rather than from the
user of http explicitly deciding they want ISO-8859-1 in particular. For
example, this gets called with an encoding that's derived from the response
headers. In cases like that, I think it's better to garble the non-ASCII text
(which may not even exist) than to just crash.

Ditto.
