All of a sudden my webpage has started to show the small black diamond with question mark inside (,in place of fractions) I have changed nothing, I have done a lot of research today, and it seems like it stems from the charset, the browser is set to unicde (UTF-8) when I change it to western (windows-1252) it corrects the problem but on reload converts back to UTF-8 and issue remains, my website was written many years ago (not by me), so any help or advise would be fantastic
