special chars when using vanilla framework

hutstein

I'm using Vanila as forum on an intern website where I make the authentification of the users via the lussumo framework. I include it this way:

require('/vanilla/appg/settings.php'); require('/vanilla/appg/init_vanilla.php'); if (!$Context->Session->UserID) header('Location:vanilla/people.php?PageAction=SignOutNow&ReturnUrl=http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);

but when i enable this code snippet all the special chars like äöüß ... are displayed as a question mark in a black square.

What make i wrong, the same data are displayed properly on a frontend page...

Sounds like a problem with the charset of the page it's creating. including init_vanilla includes a ton of other pages, one of which is headers.php which i believe sets the charset. Try playing around with that?
