feed), and U+000D (carriage return).

I mostly agree with that, with a further expository note that says that
there WILL be some cases (such as examples) where characters outside of
US-ASCII will be allowed, so downstream formats MUST be prepared to handle
them in some manner, even if that manner is not pleasant to read.

UTF-8, but that's a separate point.

I also agree with this. I'd like to leave the issue of where codepoints >
U+007F can be used completely up to the standards of future generations,
encoded in the style guide, up for renegotiation at any point that makes
sense according to community input with the RSE's expertise as final
