I'm working on one wiki which shows characters in a weird way. UTF-8 is used for encoding, so I believe that it isn't an issue.

You can take a look here Statik A – Sub Bavaria (sub-bavaria.de), so you can better understand what I'm talking about.

Could you please point me to something that I should look for, so I can fix this issue?
Wiki was previously on version 1.31, I've upgraded it to 1.38.

Thanks for your help and understanding!

Best regards,
