If you're referring mostly to the GNS, it's the fault of the person who is writing the post. The information stored in the database doesn't recognise special characters like the ones used in MS Word.
So if you use the standard ' or " in Notepad, it comes out fine. If you do it in Word and get the special curly versions, it screws up into those random symbols once it's stored in the database.
Given that it's a known, recurring problem, people really should be smart enough to avoid it. Sadly, that's not the case in practice.
