The agenda follows.

  * P2728R1 <https://wg21.link/p2728r1>: Unicode in the Library, Part 1:
    UTF Transcoding

P2728R1 <https://wg21.link/p2728r1> addresses some of the feedback
provided by SG16 during review of P2728R0 <https://wg21.link/p2728r0> in
the 2023-03-22
<https://github.com/sg16-unicode/sg16-meetings#march-22nd-2023> and
2023-04-12
<https://github.com/sg16-unicode/sg16-meetings#april-12th-2023> SG16
meetings as enumerated in the Changelog
<https://wg21.link/p2728r1#changes-since-r0> section. In this meeting,
I'd like to focus on answering the following questions with the goal
being to better understand which parts of the proposal do or do not have
support by participants.

  * Do we want to expose concepts for UTF iterators, pointers, and
    ranges (we can always have exposition-only concepts)?
  * Are concepts that distinguish between iterators and pointers useful
    (note that a pointer does not imply a contiguous range)?
  * Do we want the null_sentinel_t type?
  * Do we want to expose the constants and utilities?
  * Do we want the transcoding iterators?
  * Do we want the transcoding views and view adapters?

Tom.
