Yeah, of course - but that's why I've posted it here and not in the actual support forums.
I could imagine that someone (who simply retired a forum based on phpbb2) had similar problems and maybe could share experiences/tips on how to display all database content correctly.
By the way, when I use "View"-"Text Encoding" in the browser and set it to "Automatic", it displays fine!
But obviously, it should display correctly by default...
