I see odd symbols in Firefox too. It's most likely an encoding problem. The weird A's are there 'cause they are present in the text. Turn on all symbols in Notepad++ (View > Show Symbols > All) and those A's will show up as xC2. Did you copy/paste the text from Word or something? Double quotes (and many other symbols) in Word can not be used directly in HTML, you'll have to use “ and ” (see https://duckduckgo.com/?q=html+entities).
