使用Dejavu字体时，DOMPDF输出到服务器时不显示文本

Question

Had one of you ever problems when you save a PDF on the server with DOMPDF and if you want to look/open the PDF on the server, afterwards don't see characters but blocks instead?

I have the following for output.

//Download PDF
$dompdf->stream("Invoice: ".$row['number'].".pdf", array("Attachment" 
=> true));
//save the pdf file on the server
file_put_contents('uploads/'.$row['number'].'.pdf', $dompdf- 
>output()); 

And this for styling:

*{ font-family: DejaVu Sans;}

@font-face {
      font-family: "DejaVuSans";
      font-style: normal;
      font-weight: normal;
      src: url('fonts/DejaVuSans.ttf') format('truetype');
    }
