First I have to say thank you for this great plugin!
Now to the bug. I think there is a problem with saving with the right encoding in utf-8 to display german "umlaute" (ä,ö,ü).
For example: I exported this site http://www.ybuzz.social/ with the really static plugin to this site http://www.buchveroeffentlichen.de/ybuzz-static/
But now the german "Umlaute" are displayed wrong on the static site.
I hope you have an idea to help me with this problem.
Thanks a lot!
