Problems with decription text when sharing

Hi there,

I’ve got a problem, with the description when I share something. Instead of a nice text, I get something like this:

I don’t know why Facebook doesn’t like my wordpress. It doesn’t matter wheather I post a direct link of Facebook or wheather I use the “recommend” button on my website, the result is still the same. It looks to my like it isn’t utf8-based text, but I’ve check all my files and they all are in the utf8 code. If you’d like to see that for yourself, then here is my website:

Thanks for helping me 🙂
