Arabic characters aren't showing up properly

The courses I downloaded ages ago display fine but the new ones I’ve tried to start all display the Arabic characters as random bits or shapes like the font isn’t recognised.

Is there something I need to download to make them display correctly? I’m using an android lenovo a10 tablet.

Please help, this is soooo frustrating and I can’t find any answers by googling it.
