Came across this great cheat sheet listing many of the special HTML characters (or glyphs) we, as web developers, come across from time to time. In addition to listing the the HTML code, the chart also lists the numeric code; a description of the character; the HEX code; the ISO in CSS content (for use with pseudo-selectors like :before and :after); and the Octal (I'll be honest, I've never had to use this one before). All in all, a super-handy reference sheet to have around. Thanks to CSS-Tricks.com for yet another great resource, and to Chris Coyier for all the effort he puts into that great site.
