UTF-8

I have problems on my new page-[slug] with characters ?,?,?. It’s fine on the other pages so what could be wrong?

(this is the page if it’s of any interest: https://www.makeupedia.se/produkter and sorry for the large ads in advance)

In header.php:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
