Re: [SG16] [isocpp-core] Updated draft revision: D2029R3 (Proposed resolution for core issues 411, 1656, and 2333; numeric and universal character escapes in character and string literals

From: Tom Honermann <tom_at_[hidden]>
Date: Fri, 11 Sep 2020 10:12:40 -0400
The updated revision, with additional changes suggested by Jens
elsewhere in this email thread, has been submitted for the next mailing
and is available at https://isocpp.org/files/papers/P2029R3.html.

If anyone has any further review comments, please let me know!

Mike, I believe this is again ready for Core review. I know Core is
continuing to work through Davis' lookup paper, please let me know when
you can fit it in.
