Issue 1005: Annex D refers to option removed from UAX#31 in revision 39

Status: Review

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.

Suggested correction

Remove C23 D.2.2 (Restricted Format Characters).

Comment from Issues list maintainer on 2025-09-01:

At the August 2025 (Brno) meeting of WG14, the suggested correction was accepted, subject to review at the next meeting.

Proposed correction

Remove C23 D.2.2 (Restricted Format Characters).
