> No quotes will be added, as your delimiter does not occur in the text value.
How does this feedback fit to previously provided information?
A)
https://docs.basex.org/wiki/CSV_Module#Options
“…
Serialization: If the option is enabled, the value will be wrapped with quotes if it contains characters that might be treated as control characters.
…”
B)
https://mailman.uni-konstanz.de/pipermail/basex-talk/2022-April/017038.html
“…
The double quote is the text qualifier that’s used for serializing fields with spaces.
…”
Another XQuery script example:
declare option output:method "csv";
declare option output:csv "header=yes, quotes=yes, separator=|";
<csv>
<record>
<T3>line 1
line 2?</T3>
<T4>line 3\nline 4?</T4>
</record>
</csv>
Test result:
T3|T4
"line 1
line 2?"|line 3\nline 4?
Will any more clarification help here?
I confess that I'm not sure, but if you're asking "Why are there double quotes around my `T3` field?", then the answer appears to be in the CSV specification[1]. So, the behavior you're seeing in your sample script matches the CSV RFC.
If that wasn't your question, it might help to restate, or reframe, your questions and concerns.
