Special character problems; not showing images on Apple devices

Hello, my dear hero that will hopefully help ??

I love the AccessPress theme mag lite (free). Today was our launch of our www as promised to our readers, but sadly we found out that some problems are preventing us to start.

1/ special characters are not displaying correctly all across mobile devices (Apple n Android) and also some old PCs. ?, ?, ě, etc. We’re using the Czech language. Can send a screenshot with this email. But as the page is live, now – the easiest is to have a look at it.

2/ and some images (they all seem to be set the same way) not showing all across Apple mobile devices (iPad, iPhone). Kindly look at the website for more.

I’d appreciate a prompt help! Paying gold;)
Thank you very much,
