I've just rediscovered Oxwall as a possible script for a new website and did a quick install using Softaculous to testride it and like the way things have developed since I last checked it out. 

But.. one of the features I'm really looking for which is actually my main feature for an upcoming project is link preview possibilities. 

I tried this on my test site but Scandinavian and German letters come out as code  ( ö för ö) in the preview and not like the letter. 

Any way to solve this problem in an easy breezy way?
