I generate a PDF from symfony2 with the library wkhtmltopdf. The html is a twig layout with some variables to display. The generation works but stranges symbols replace latin caracters. If I copy-paste symbols in notepad, I can read letters. In my twig header, i put
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
I find, my linux server hasn't good package installed for font... I just do this :
sudo yum install urw-fonts libXext openssl-devel
and it works nice !
