Yes, I understand this part of the situation.

My question was meant to see if there's a way to encode a similar kind
of charset info into the bytestream.  From what you say above, there is
such a thing but its use is discouraged.

Clearly this problem is not specific to Emacs, so what do people do?
Hold on to iso-2022 for as long as they can (like we do in Emacs)?
Give up on these "details" of rendering for files using a mix of C, J, and K?
Rely on higher-level info (XML tags and friends) to carry the charset info?
