Question Marks in Wordpress Posts...

I've been configuring a server for Wordpress for quite sometime now. I'm having an issue with posts coming up with question marks in the spaces when I copy and paste.

The posts have to be typed in manually, but this can be a time waster as the posts are already typed from before.

I'm pretty sure it's a server issue and I might be setting up something wrong, but I'm not sure what I'm doing on the server. Can you help me figure this out?
