Facebook share displaying weird characters

I just added a facebook share icon to my website, when I hit the button the facebook popup displays weird special characters

the character won't display here but it's a square with 00 over 97

for example instead of a single quote

I tried changing the quote to a the special character ’ but this doesnt' work either

also tried messing with the charset, but then i'd need to use a special character everytime i need to display a quot开发者_JAVA技巧e.

My site is mostly text-based so I don't want to get involved in that.

Any suggestions?

<meta http-equiv="Content-type" content="text/html; charset=utf-8" />

Put this meta tag in you HTML page, facebook uses UTF-8.
