That's what I was wondering. Is triggering CSV for multi-character
delimiters a little too clever? This reminds me of the use of LIMIT X,Y
with no indication which is limit and which is offset.
We certainly could code to prevent the multibyte problem I mentioned,
but should we?
I am thinking just:

or

EQUOTE for embedded quote. These are used in very limited situations
and don't have to be reserved words or anything.
I can help with these changes if folks like them.
