CMS issue only in Firefox

[sepunx2]

Hi!
I installed a content management system on my site, called fusionnews.net. Everything works fine, but in Firefox, it gives me a lot of weird characters. It seems like they are unable to help me on their forum, so I figured I should look for help here, because it might be a css coding issue too.
Here is the link: http://falcongaterock.com/ENG/engindex.php
The funny thing is, that this only happens on the english version of the sites, everything's OK on the hungarian versions, even if they have no difference in the coding I believe.
Any help would be highly appriciated,
Thank You

It's solved. It was a simple charset problem.
Thank You
