Expect clang to support Unicode 15 soon, i did the pr earlier today.
In general because Unicode releases faster than C++, vendors should update
without waiting for the standard to catch up, in order to support new

How many references to Unicode do we have?.
Most of the wording sadly relies on iso 10646 which doesn't get updated as
fast.
