Now that the proposal has been accepted, I'd refer to C++2a instead.

Agreed.  I also need to make the changes to implicitly enable -fchar8_t with -std=c++2a.

The list of impacted standard library features was incomplete and I suspect it isn't worth mentioning them specifically.  Perhaps mentioning the feature test macros would be helpful as well?

How does the following sound?

Enable support for @code{char8_t} as adopted for C++2a.  This includes the addition of a new @code{char8_t} fundamental type, changes to the types of UTF-8 string and character literals, new signatures for user defined literals, associated standard library updates, and new @code{__cpp_char8_t} and @code{__cpp_lib_char8_t} feature test macros.
