LWG has tentatively approved
<https://github.com/cplusplus/papers/issues/977#issuecomment-1107071392>
P2286R7 as linked above pending SG16 confirmation of design intent and
wording for non-Unicode encodings. Please review the SG16 2022-01-26
meeting summary
<https://github.com/sg16-unicode/sg16-meetings#january-26th-2022> for
previously discussed concerns. A few wording details are still being
discussed outside of the mailing lists, so the paper revision linked
above may still receive some updates prior to our meeting.

Further review of P2558R0 and D2572R0 are scheduled pending updates from
the authors to address feedback from the SG16 2022-04-13 telecon
<https://github.com/sg16-unicode/sg16-meetings#april-13th-2022> (which I
have yet to publish).
