Strange Charcaters  in Firefox on Top Of Page

I was struck with  the strange characters at top of page in Firefox
These characters was NOT in IE or Opera

The Cause was

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

at Top Of page,looks FF has problem in charset type

simply removing this line solve the issue

Through I guess mentioning META charset type is a good idea but I will think about that later
