From: Tom Honermann <tom_at_[hidden]>
Date: Sat, 10 Sep 2022 09:47:36 -0400
SG16 will hold a telecon on Wednesday, September 14th, at 19:30 UTC
(timezone conversion
<https://www.timeanddate.com/worldclock/converter.html?iso=20220914T193000&p1=1440&p2=tz_pdt&p3=tz_mdt&p4=tz_cdt&p5=tz_edt&p6=tz_cest>).

The agenda is:

  * Report on the on-going interactions between WG21 and the Unicode
    Consortium.
  * Report on the backward compatibility impact of P1949 (C++ Identifier
    Syntax using Unicode Standard Annex 31) <https://wg21.link/p1949>.
  * Continued discussion of P2626R0: charN_t incremental adoption:
    Casting pointers of UTF character types <https://wg21.link/p2626r0>.

SG16 has previously engaged with the Unicode Message Format Working
Group (MFWG) <https://github.com/unicode-org/message-format-wg> (in our
March 11th, 2020 telecon
<https://github.com/sg16-unicode/sg16-meetings/blob/master/README-2020.md#march-11th-2020>)
and the Unicode Source Code Ad Hoc Group (SCAHG) (in our May 25th, 2022
telecon <https://github.com/sg16-unicode/sg16-meetings#may-25th-2022>
with Robin Leroy). Peter and Tom have continued engaging with these
groups. Tom will report on their activities (Peter is not expected to be
available for this meeting).

Implementation of P1949 in Clang (as a DR unconditionally applied to
older language modes) prompted some users to report substantial impact
to projects that previously enjoyed use of mathematical symbols in
identifiers. Tom will report on some specifics of the impact, discussion
between Clang implementors, and on-going work by the SCAHG that may
provide a solution in the future. Further discussion should focus on
guidance that we may want to offer to implementors.

Pending Corentin's availability, we'll continue discussion of P2626R0
from our August 24th, 2022 telecon
<https://github.com/sg16-unicode/sg16-meetings#august-24th-2022>.

Tom.
