As a quick follow-up, several of the points made in the new paper:

    P2491 Text encodings follow-up (Jens Maurer)
    https://wg21.link/p2491r0

rest on the discrepancy in the specification of the UTF-16 encoding scheme between the Unicode Standard 14.0.0 and ISO 10646:2020. The project editor for ISO 10646 believes this to be a defect which will be brought into line with the Unicode Standard in the next revision of ISO 10646, which is currently being prepared.

I hope that P2491 can be revised to mention this.

Best regards,
