I have a question regarding the content copied from the query results window.
Let's say I run a query that contains a line feed character.
select 'Hello' output from dual
union all
select 'grand '||chr(10)||' universe' from dual;
When I copy the results from the query result

And paste it somewhere, it surrounds any content that contains a line feed with double quotes.
Hello
"grand
universe"
My preferred output would be
Hello
grand
universe
I tried using the worksheet hint after modifying the left/right enclosure for the Export: Text Format options (as described here)
select /*text*/ 'Hello' output from dual
union all
select 'grand '||chr(10)||' universe' from dual
"OUTPUT"
"Hello"
"grand
universe"
But I guess you could say that made the problem worse.
Though I'm not sure the setting was effective, because when I unchecked “header”, the “OUTPUT” was still displayed.
I'm currently on 21.4, but have no reason not to upgrade (just haven't got around to it)
