[Q] Missing letters in the S6 system

Hello.

I got the Samsung Galaxy S6 on the 11th of April this year.
But I've been having som problems since then.
When I use the phone some letters isn't showing (see photos). It's everywhere from the clock on the lockscreen, messages app, to games.

I was wondering if anybody knows about this?
Samsung in Denmark says that I'm the only one they heard of who had this problem.
So I was curious.

Thanks in advance.
