About a year ago I submitted an RCF on iconv() in
XL C/C++ Runtime Library Reference. The text has been
changed in the 1Q21 refresh. It now reads:
https://www.ibm.com/docs/en/zos/2.4.0?topic=functions-iconv-code-conversion
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.|>
... where it had previously said "implementation dependent". But
is "substitution character" intuitively obvious? would it be better
to say "the SUB character of the target character set" *and* provide
a citation?
The wonderful zOSV2R4-Search-Index.pdx shows 24 z/OS documents
containing "substitution character" with various meanings.
BTW, the two occurrences of "is to be" don't strike me as colloquial
English. Should I mention that?
For pitfalls, see, e.g.:
