Hi,

I am using Dompdf to download html contents in pdf. It works fine for english, but it does not detect Indian fonts.

The following is my code:

$html = mb_convert_encoding($contents, 'HTML-ENTITIES', 'UTF-8');

$dompdf = new Dompdf();
$dompdf->loadHtml($html);
$dompdf->render();

$dompdf->stream();

for Indian languages, it outputs "??????????????" . Also the font-size for Indian fonts is very small Could you please help me resolve the issue?

Thanks,

I am working on my first Drupal 8 website, and I am trying to learn it's framework and systems as I am entirely used to Drupal 7 development. I am trying to build a module that allows authenticated users on my website to link their Steam ID to their account.

There is a library called LightOpenID which is used for this (steam has light open ID support), but I am having difficulties getting it to work with Drupals routing system.

I'm am trying to write a module that will assign a role to a user on once they have purchased a product (Drupal 8.8.2, commerce 8.x-2.16). I have googled and there are bits and pieces (e.g. "write a new class called an event subscriber to assign that user role on the "placed" transition") that suggest how this could be done.

Hello,

We are creating a mobile game and we're evaluating Drupal for the back end.  We want to use Drupal to store the accounts and use Game Center for iOS and Google Play Games for Android to authenticate the user.

Has anyone done this and can someone send me in the right direction for a link or tutorial for this?

Thank you in advance.
