Proposed resolution (approved by CWG 2023-01-27):
Change in 5.13.3 [lex.ccon] as follows:
hexadecimal-escape-sequence :
\x hexadecimal-digit simple-hexadecimal-digit-sequence
hexadecimal-escape-sequence hexadecimal-digit
\x{ simple-hexadecimal-digit-sequence }
Date: 2023-02-15.00:00:00
[Accepted at the February, 2023 meeting.]
The lexer grammar production hexadecimal-escape-sequence matches text of the form \x{20}ab due to its recursive definition.
