Not sure what it is but I would try changing your charset from:
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
thanks osgood for your reply, as per your instruction. i am changed entire website, but nothing is happend
Nothing will happen right away until the Google spider returns and reads the page again.
I don't even know if the charset is the issue BUT I can't see anything else in the page that could be returning the strange sequence of letters.
