You would only see the glyphs if you have a font installed that covers this Unicode range. Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)? *https://en.wikibooks.org/wiki/Unicode/Character_reference/F000-FFFF <blockquote>Unicode range E000–F8FF is used as Private use area which is reserved for private use. Unicode and ISO/IEC 10646 do not assign characters to any of the code points in this range. The repertoire seen with your computer's font will most likely not be the same as with other computers or fonts.</blockquote> Fonts that fall in this Unicode range are usually downloaded from the server. Missing icons are usually supplied by a font that is downloaded from the server (@font-face) as you might see by little boxes that show the hex code of the characters instead. If you have a font installed that covers this Unicode range then you may see a real (CJK) character and not the little box with the CSS code. Make sure that you allow pages to choose their own fonts. *Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above" You can check the <b>gfx.downloadable_fonts.enabled</b> pref on the <b>about:config</b> page and make sure that it is set to true (if necessary double-click the line to toggle its value to true). ----- Wingdings isn't part of this PUA range. *http://www.alanwood.net/demos/wingdings.html *https://en.wikibooks.org/wiki/Unicode/Character_reference/2000-2FFF You can install the Symbola font via this website: *http://users.teilar.gr/~g1951d/
