We will be discussing the following papers:

P2314R2 (https://wg21.link/p2314r2) Character sets and encodings
Proposes to change C++ to use the "Model C" approach to
universal-character-names from C99 and introduce a new term of art to
describe literal text encodings. The author is looking for feedback on
the proposal, especially feedback on whether new incompatibilities
with C are being introduced by the changes to handling universal
character names.

P1997R1 (https://wg21.link/p1997r1) Relaxing Restrictions on Arrays
Proposes initialization, assignment, and function return for arrays
directly which is currently prohibited in both C and C++. The authors
ask for feedback on the topic and advice or volunteers to champion the
idea in WG14, as well as polls to forward the paper to EWG and/or
revise to deprecate array types in e.g. function parameters.

P2340R0 (https://wg21.link/p2340r0) Clarifying the status of the “C headers”
Proposes to undeprecate the C headers within C++ so that users need
not fear they will be removed in the future. The paper has been
approved by LWG in C++ and is anticipated to be adopted for C++23. The
author expects this to be an informational presentation, but is
interested in feedback if the proposed changes cause compatibility
