Bad characters when generating pdf file with Knp Snappy - php

Question

I am using Symfony2. When the pdf file is generated using this code :
public function printAction($id)
{
// initialiser $demande
$html = $this->renderView('PFETimeBundle:Demande:print.html.twig',
array('demande'=> $demande)
);
return new Response(
$this->get('knp_snappy.pdf')->getOutputFromHtml($html),
200,
array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="file.pdf"'
)
);
}
I get this content (french characters appear in bad characters) :

Answer 1

try to add the encoding property
'encoding' => 'utf-8',
heres a full copy of my working code, pls note that i pass an options array as second argument to getOutPutFromHtml()
return new Response(
$this->get('knp_snappy.pdf')->getOutputFromHtml($html, array(
'orientation' => 'landscape',
'enable-javascript' => true,
'javascript-delay' => 1000,
'no-stop-slow-scripts' => true,
'no-background' => false,
'lowquality' => false,
'encoding' => 'utf-8',
'images' => true,
'cookie' => array(),
'dpi' => 300,
'image-dpi' => 300,
'enable-external-links' => true,
'enable-internal-links' => true
)),
200,
array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="report.pdf"'
)
);

If you are using the generateFromHtml method, you have to use it like this, at third parameter:
$this->container->get('knp_snappy.pdf')->generateFromHtml(
$this->container->get('templating')->render(
'YourBundle:Template:pdfTemplate.html.twig',
array(
'var' => $var,
)
),
'/path/to/file.pdf',
array(
'encoding' => 'utf-8',
)
);
