--- Comment #1 from James K. Lowden <jklowden at gcc dot gnu.org> ---
The reference is to Table 10 in ISO/IEC 1989:2023, and the assertion is
correct. I am not sure how to reduce Table 10 to a set of rules, given the
complexity and many exceptions. ISO would do the world a service by expressing
the same rules as regular expressions. (Good luck with that.)
Nevertheless, more could be done to screen out invalid pictures.
> note: U is nearly identical to N
Meaning, U as defined by IBM? It's not in ISO.
