I found a diagonal arrow in the symbol typeface "Wingdings 3" that I'd like to use but I can't get it to work. The typeface is installed on my system (osx 10.8) and I even tried to embed it using @font-face. The letter that corresponds to the arrow is "k", but the only thing that renders in the browser is the actual letter, k, and not the arrow. Does anyone know why this isn't working? I was also unable to use other symbol typefaces, like Zapf Dingbats.
