I just started to see some weird characters in my wordpress site. It messed up the '-' sign and even for the copy right sign now I see "©". If I clear the Wp-Super cache, these characters will disappear for some time. But then it come back again. Why is it happening? How to fix it?

Update : You can see the issue in this website : http://cybergnome.com/ . Scroll to the bottom and see the copyright information in the footer.

Add a sample link to your question. – toscho♦ Nov 4 '12 at 17:44
@toscho Sorry for that... Just added the link :) – EApubs Nov 5 '12 at 2:04
You forgot to add charset utf-8; to the server {} declaration of the NGINX configuration, hence the server doesn’t send a charset information, and your UTF-8 is read as Windows-1252 (or some other single-byte encoding). But that is a server configuration issue and therefore off topic here. Try Server Fault if you need better help with that. – toscho♦ Nov 5 '12 at 2:11
