Ruoso, wouldn't Text::CSV and related modules (XS, PP) work for you? I suppose you know this module, so what am I missing?

#!/usr/bin/perl -w 

use Text::CSV_XS;

my $csv = Text::CSV_XS->new( { 'escape_char' => '\\' } );

my $line = '"This is a column","Yes, I know",12323,23123.23,"This is a
+ \"column\""';

if ( $csv->parse($line) ) {
    print join "\n", $csv->fields, "\n";
}
else {
    print "Could not parse line\n", $csv->error_input, "\n";
}
