Proposed resolution (approved by CWG 2025-11-04):
Change in 5.3.2 [lex.universal.char] paragraph 1 as follows:
... If a universal-character-name outside the c-char-sequence,or s-char-sequence, or r-char-sequenceof a character-literal or string-literal (in either case, including within a user-defined-literal) corresponds to a control character or to a character in the basic character set, the program is ill-formed. ...

(From submission #785.)
Subclause 5.3.2 [lex.universal.char] paragraph 1 specifically excludes universal-character-names within r-char-sequences, but universal-character-names are never formed there.
