I've checked the 2020 September refresh.

Is this affected by the update to SC14-7314-40 (see below), and my
addiitonal comments.

Now, with revision bar:
If iconv() encounters a character in the input buffer that is valid, but
for which a conversion is not defined in the conversion descriptor, cd,
| then the substitution character is to be put in the target buffer and the
| conversion is to be continued.
I feel that "substitution character" should be further clarified to
"substitution
character (SUB) of the target character set".
("is to be" isn't colloquial English.)
