std.csv will reject this. If validation is turned off this is 
fine but your data will include "".

"A field containing new lines, commas, or double quotes should be 
enclosed in double quotes (customizable)"

This because it is not possible to decide what correct parsing 
should be. Is the data using including two double quotes? What if 
there was only one quote there, do I have to remember it was 
their and decide not to throw it out because I didn't see another 
quote? At this point the data is not following CSV rules so if 
I'm validating I'm throwing it out and if I'm not validating I'm 
not stripping data.
