C23 D.2.2 (Restricted Format Characters) refers to an option UAX#31-R1a that appears to have been removed in revision 39 of UAX#31 (the current revision as of this writing is revision 41).
This subclause should thus be updated or removed. See reflector message 25125 for some relevant references. It would be best for our Unicode experts and C++ liaison to establish what fix is best and most compatible with C++, but in the absence of that I propose the obvious minimal change.
Remove C23 D.2.2 (Restricted Format Characters).
