Thank you. That is at least three people reporting they found the prior
wording for the hex formatting to be more clear, so I'll restore that.

Yes, I had thought about that, but hoped it was clear enough. Clearly it
wasn't. Thank you.


I think I have applied this. Here's the rendered version: https://brevzin.github.io/cpp_proposals/2286_fmt_ranges/p2286r8.html#pnum_12

And here's the diff, which may or may not be easier to read: https://github.com/brevzin/cpp_proposals/commit/0376912a9e1976e947016b1c393a356af6afa5d0

One thing I noticed is that the wording about Grapheme_Extend is gone. I didn't know what this meant before, so I don't know now if this is a good removal or a bad removal.

How does this look?

Thanks, Barry, but additional changes will be needed. We discussed the suggested wording during the SG16 telecon last week, but don’t have consensus on the updates quite yet. I just published the notes from the meeting an hour ago to https://github.com/sg16-unicode/sg16-meetings#april-27th-2022

I had intended to follow up with revised wording by now, but have instead been spending my time recovering from COVID. Sigh. I’m on the mend and will follow up tomorrow or Friday. 


Thank you all,
