I'd say it would be best to only accept `bytes` objects; anything else
would require some guesswork. Maybe, at most, it could try to encode
returned Unicode objects as ISO-8859-1, and have it be an error if
that's not possible.
I was going to say that the gateway could accept Unicode objects if
the user-agent sent a comprehensible Accept-Charset header, and
thereby encode application output to the client's preferred character
set on the fly (or to ISO-8859-1 if no Accept-Charset is provided),
but that would complicate things for people writing gateways (and
would be too implicit). It could be useful, but it would make more
sense as a simple decorator for (almost-)WSGI applications. Perhaps it
could go in wsgiref.
