Let's put a little flesh on those a's and b's:
A typical example of the first case is where a database address line
contains a quoted house name e.g.
"Dunromin", 123 Main Street
and the producer of the CSV file has not done any quoting at all.
An example of the 2nd case is a database address line like this:
C/o Mrs Jones, "Dunromin", 123 Main Street
and the producer of the CSV file has merely wrapped quotes about it
without doubling the existing quotes, to emit this:
"C/o Mrs Jones, "Dunromin", 123 Main Street"
which Excel and adherents would distort to two fields containing:
'C/o Mrs Jones, Dunromin"' and ' 123 Main Street"' -- aarrgghh!!
People who complain as described are IMHO misguided; they are accepting
crap and losing data (yes, the quotes in the above examples are *DATA*).
Why should we heed their complaints?
Perhaps we could consider a non-default "dopey_like_Excel" option for
BTW, it is possible to do a reasonable recovery job when the producer's
protocol was to wrap quotes around the data without doubling existing
quotes, providing there were an even number of quotes to start with. It
just requires a quite different finite state machine.
