The meta info knows whether the field was quoted or not.

True, though AFAICT the meta_info doesn't seem to keep track of escaped characters:

use warnings;
use strict;
use Data::Dump;
use Text::CSV;

my $csv = Text::CSV->new({ binary=>1, auto_diag=>2,
    keep_meta_info=>1, escape_char=>"\\" });
while ( my $row = $csv->getline(*DATA) ) {
    dd $row, $csv->meta_info;
}
$csv->eof or $csv->error_diag;

__DATA__
foo,bar
"#foo","bar"
#foo,bar
\#foo,bar
