If you use something "fancy" you may find they are not available on

I've used a WP TypographicSymbols bullet in my website, which isn't using
a FP theme, and this bullets appears as a $ on some browsers, particularly
Mac ones. I use Internet Explorer and the bullets look fine when I view my
website.
