Microsoft Typography has created another great font for Web surfers and, as usual, it's free. Webdings is a TrueType symbol font for the Web. The font will be included with Internet Explorer 4 and available separately for free download. The font contains over 200 of the most asked-for symbols and most of the entities listed in the W3C's working draft on HTML predefined icon-like symbols.
As with all of Microsoft's free fonts, I recommend that you download Webdings immediately.
