If you want to suppress the quotes, you can use quote_char (note: I'm using a more recent version of Text::CSV):

use warnings;
use strict;
use Text::CSV;
print Text::CSV->VERSION . "\n";
print Text::CSV->version . "\n";# The version of the worker module
my @array = ('REGR_EMEA_UK_CONF_CUST1_BAN ??e???ta?');
my $csv = Text::CSV->new({quote_char => ''});
my $status = $csv->combine(@array);
print $csv->string() . "\n";
exit 0;
