"/n" show after return line in pdf - php

Question

I am trying to generate a pdf file via the dompdf library (the displayed values ​​come from a mysql database), and I have an encoding problem. I did a lot of research but without success.
The problem is that at each line break, a "/ n" is displayed.
I tried to use different functions html_entities_decode, nl2br and even str_replace ("/ n", "", $ str), but could not delete it.
The "/ n" is not registered in the database at the specified value. I looked in the source files dompdf and it does not come from there either.
A big thank you in advance for your responses !
CODE
use Barryvdh\DomPDF\Facade as PDF; // Barryvdh use dompdf
// function used
public function downloads($from, $type, $unique_id, $downloads, $dom, $do) {
$data['from'] = $from;
$data['type'] = $type;
$data['unique_id'] = $unique_id;
$data['title'] = 'PDF Generation';
//User Details
$userController = new userController;
$data['logeduser'] = $userController->logeduser();
$userpermissions = $userController->getpermissions();
//Notification Details
$notification = new notificationModel;
$data['notification_list'] = $notification->getAllRemainder();
//PDF Generation
$sales = new salesModel();
$data['offer_sav'] = $sales->getOfferSAVDetails($unique_id);
$data['offer_sav_products'] = $sales->getOfferSAVProductDetails($unique_id);
$data['offer_eg'] = $sales->getOfferSAVDetails($unique_id);
$data['offer_eg_component'] = $sales->getOfferEGComponent($unique_id);
$data['offer_eg_accessory'] = $sales->getOfferEGAccessory($unique_id);
$data['offer_eg_options'] = $sales->getOfferEGOptions($unique_id);
$data['sav_eg_without_sm'] = $sales->getSAVEGWithoutSM($unique_id);
//view()->share($data);
//return view('sales/pdfonly', $data);
$pdf = PDF::loadView('sales/pdfonly', $data);
//$view = view('sales/pdfonly', $data);
//$pdf = PDF::loadHTML($view);
if(!empty($_GET['print']))
return $pdf->stream('pdf_'.$from.'_'.$type.'.pdf', array("Attachment" => 0));
else
return $pdf->download('pdf_'.$from.'_'.$type.'.pdf');
}
// exemple of code output
