Additional notes (January, 2023):
Forwarded to SG12 with paper issue 1409, by decision of the CWG and SG12 chairs.
(From National Body comment US 142 on the C++20 DIS.)
Subclause 15.6.3 [cpp.stringize] paragraph 2 specifies:
If the replacement that results is not a valid character string literal, the behavior is undefined.
Undefined behavior during lexing is not acceptable. This ought to be ill-formed.
