What Firefox/Win (and, incidently, Opera) is doing is correct. Your HTML
markup has the characters '5' and '6'. They don't exist in the Webdings
font, so the browser can't display them. It might be more correct to say
that Webdings can't display ISO-8859-1 characters.

Anyway, the correct solution is to put the correct characters into the
markup, namely ▲ and ▼. I got those from the Unicode character
charts <http://www.unicode.org/charts/>, specifically the "Geometric
Shapes". Note that the hexadecimal Unicode codes need to be converted to
decimal.

Webdings and similar fonts (eg Wingdings) really shouldn't be used at all.
Always use Unicode for this sort of thing.
