Sounds good to me, but SG16 should review first. I anticipate such review occurring during one of our two February telecons.

Since it's not a new feature, but rather a bugfix, then we still have time to make it to 23. Would you want me to do so? I haven't scheduled EWG meetings fro 2022 yet, giving everyone a break.

Dear Jens,

     I had no intention of filing (or asking someone to file) an NB comment, albeit now that the paper is released I don't think I could stop someone from doing it. I don't mind if it's C++26 material because it's a DR, so it would always apply to C++20. (Albeit, it's probably better if it's fixed sooner rather than later.)

     If EWG can squeeze it in and everyone's fine with it, I'll try to attend an EWG meeting and answer questions and get it forwarded so I can do CWG -> plenary for C++23!

Originally, I was dabbling with the idea of adding pointer conversions from UTF-8 string literals (and only UTF-8 string literals) to (in order of preference for overloading and conversion ranking) const char8_t* -> const unsigned char* -> const char*, but that paper would be COLOSSAL. I'd likely require an implementation to prove it works in practice, too, since it would touch conversion rules, ranking, and overload resolution.

The "target" of the paper says C++26.

I thought you wanted it considered as a C++20 bug fix,
which should go into C++23 ?

It's certainly short enough and bug-fixy enough to go through
EWG and CWG in the coming months, and I'd rather have it
discussed now as opposed to dealing with an NB comment later.

I also changed "can" in the previous sentence to "may" as well, so we don't have a weird can/may or may/can split. Updated paper here: <>
