We lack a term for that today (which is why the paper uses the phrase "encoding of the execution character set"). But that is different from what is intended by "associated character encoding"; this is intended to name an encoding (possibly indirectly, hence "encoding of the ...") that might be registered with IANA <https://www.iana.org/assignments/character-sets/character-sets.xhtml> (where the term "character set" is used to mean "character encoding", but the former is used for legacy reasons).

You lost me there.

What does IANA's list of character sets/encodings have to do with
how a compiler chooses to encode C++ literals?

Maybe the compiler has invented an encoding of its own, just
for the fun of it.

If you intend some stronger relationship to IANA here, this
needs to be a lot of explicit.
