- mezzoblue | Glyphs, which demonstrates how troubled the unicode character set is at the present time. For example, my Win2k Pro machine at work showed a partial set in all browsers; with Opera only missing about three. However the really odd thing was that Firefox/Netscape 8 showed a different version of the glyphs.
- The Trouble With EM 'n EN (and Other Shady Characters): A List Apart. But you've already read that one, right? It's a nice roundup of the different dashes, hyphens and other typographically correct characters.
- A Simple Character Entity Chart | evolt.org
- A to Z Index of Unicode Characters: starting with 'A'. Yep. The lot. You can also use the Unicode Character Search or view Unicode Character Categories.
- HTML Codes - Table of ascii characters and symbols, a simple guide to basic characters (the most commonly used ones, anyway).
- This is where the magical link should go. You know, the one that clearly explains which character encoding you should use in your web pages and why. When I find it, I'll let you know :) I've been told both "use iso-8859-1" and "use utf-8" but when I ask for more details people shuffle their feet and look into the middle distance. Well ok, so there are some exceptions: Quick guide to UTF-8 - Anne's Weblog about Markup & Style makes a pretty good case for using utf-8.
In short... character set encoding and special character display remain a pain in the butt.
