How to enable Russian language support in Dompdf?

Question

symfony

Hello everyone
I want to convert html page to pdf. The page itself contains only html code without css. I do everything using the Dompdf extension.
Installed with Composer

public function index()
    {
        // Configure Dompdf according to your needs
        $pdfOptions = new Options();
        $pdfOptions->set('defaultFont', 'Arial');
        
        // Instantiate Dompdf with our options
        $dompdf = new Dompdf($pdfOptions);
        
        // Retrieve the HTML generated in our twig file
        $html = $this->renderView('default/mypdf.html.twig', [
            'title' => "Welcome to our PDF Test"
        ]);
        
        // Load HTML to Dompdf
        $dompdf->loadHtml($html);
        
        // (Optional) Setup the paper size and orientation 'portrait' or 'portrait'
        $dompdf->setPaper('A4', 'portrait');

        // Render the HTML as PDF
        $dompdf->render();

        // Output the generated PDF to Browser (force download)
        $dompdf->stream("mypdf.pdf", [
            "Attachment" => true
        ]);
    }

Here is a year that generates pdf, where all Russian characters are displayed as questions. I tried to register the font through the css file, embed the font in html.
Information about the client
The result is similar. How do you set the font to work?
