Cpanel WYSIWYG editor

Hi all
I always use Cpanel editor to edit content of my web site. This time something weird happens. When I saved it after I've done some editing I see something like this:
We are one of the Internet's top survey resource companies. We offer the freshest listings and only the best companies make it into our directory! Plus, we back-up our service with a money-back guarantee - Valid for up to 1 whole year!Â

and more if this stuff. Does any one know if this problem related to cPanel or is it because of my coding of the web page. Thanks in advance
