Using single, double and triple quotes in sql for text qualifiers : I am processing some CSV data from a client and one of the headers is 'booktitle'. The values of 'booktitle' are text qualifed with double quote and there are quotes in some of the titles, such as;

"How to draw the "Marvel" way"

I asked the client to escape the quotes in quotes with double quotes, and they sent me back this

'"How to draw the """Marvel""" way "'

So single, double, then triple quote. My question is will this work? I have not seen it done this way before for escaping text qualifiers.
Thanks
