Thank you for the feedback! Most of it has been applied. The paper title does say "Fixes" but this probably does just classify as a single fix, so I'll change the title. 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.
This single fix is more than enough to get us by for now, and already has ample existing practice (it was the way it was before!).
