Yes, if you're working with csv files and perl, you really should be
using Text::CSV_XS
(or DBD::CSV, which uses it internally).   Trying to hack CSV with
home grown code
is usually a mistake.

If the "binary" option is not the default yet, don't forget to turn it
on: that should allow you to put newlines inside a string.  It at
least used to be necessary to use "binary" to get it to deal with the
full range of latin-1 correctly.

Looks like I called that right:

Paul Makepeace has a point about the general nastiness of csv format.
It's a "standard" without a standard, it *looks* simple but has a lot
of funny edge cases to it, and there's no guarantee that a csv file
that's read correctly by one app will be read correctly by another.
