laravel - Dompdf problem with displaying Nepali character

in Technique[技术] by (71.8m points)

I am using Dompdf to create a pdf for my Nepali content. I have written following code in my controller:

public function generatePDF(Request $request){
  $data = $this->news->where('slug', $request->slug)->first();
  $html = "<!DOCTYPE html>
  <html>
  <head>
    <meta http-equiv='Content-Type' content='text/html; charset=utf-8'/>
    <meta charset='UTF-8'>
      <title>". $data->title ."</title>
      <style>
      @font-face {
        font-family: preeti;
        font-style: normal;
        font-weight: 400;
        src: url('{{ asset('/frontend/fonts/preeti.ttf') }}') format('truetype');
      }
      </style>
  </head>
  <body style='font-family: preeti;'>
      <img src='".$data->image ."' style='width: 100%; height: auto'>
      ". $data->description ."
  </body>
  </html>";
  $html = mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8');
  $pdf = PDF::setOptions(['dpi' => 150, 'defaultFont' => 'preeti']);
  $pdf = PDF::loadHTML($html);      
  return $pdf->download('sample.pdf');
}

But this gives ???? as an output of the Nepali content inside the canvas. However, <title>". $data->title ."</title> displays right character. What can I do to fix this?

As you can see I have kept UTF-8 in my meta also have included CSS for the font but it does not seem to work. I have also included mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'); but it made no change. Does anyone has fixed this kind of issue?

The output of $data->description is

<p>????? ????????????? ????? ????? ??????? ????? ????????? ??????? ??? ????? ?

As Mentioned in the comments, dompdf/domPDF after following the steps as mentioned above does not give the desired results, see this,

I suggest the use of TCPDF. elibyy / tcpdf-laravel provides a way to add tcpdf in laravel.
Install it using
composer require elibyy/tcpdf-laravel.

Add this to your provider in config/app.php

ElibyyTCPDFServiceProvider::class,

Then In your controller add the lines

use ElibyyTCPDFFacadesTCPDF;

public function generatePDF(){
        $data = new stdClass(); //can be your model, I have just used empty object
        $public_path = public_path();
        $data->title = "<p>??????????? ???????? ??</p>";
        $data->description =  "<p>????? ????????????? ????? ????? ??????? ????? ????????? ??????? ??? ????? ?

              font-style: normal;
              font-weight: 400;
              src:url('".$public_path."/public/PREETI.TTF' format('woff');
            }
            </style>
        </head>
        <body style='font-family: preeti;'>
            ". $data->description ."
        </body>
        </html>";
        $html = mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8');
        
        
        $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
        $pdf::setFontSubSetting(true);
        $pdf::setFont('freeserif','',12);
        // $pdf->SetFont('dejavusans', '', 14, '', true);
        $pdf::AddPage();
        $pdf::writeHTML($html, true, 0, true, true);
        $output = $pdf::Output('001.pdf', 'I');

        return $output;    
      }

Should get output like this.
