Yes, because:
. nulls are never quoted
. fields containing the quote char must be quoted

If it is correct, maybe the delimiter could also
match the escape character?

Yes, probably. Crazy, but I think it's workable. I'll take that test out, and just make sure that the delimiter is different from the quote.
