order character entities. You can order them alphabetically, by number, or by Unicode collection, to mention just a few methods. I find all of these rather arbitrary. So, I have taken the liberty of classifying them into what I consider logical categories, and sometimes subcategories, and then by alphabetical order. I hope you find it useful. And don't forget, you can always use your browser's Find command to find a particular word or phrase within this page.
For more information on how to use these entities in your Web pages, see HTML for the World Wide Web: Visual Quickstart Guide, 5th edition, by Elizabeth Castro.
