HTML Goodies. XHTML Special Characters. Character Entity References in HTML 4 and XHTML 1.0 Here is a set of tables containing the 252 allowed entities in HTML 4 and XHTML 1.0, as described in section 24 of the official HTML 4 specifications, published by the W3C. I have divided them into my own, hopefully logical, categories: Each table has five columns. The first column contains the entity reference, in the form &entity_name;, that is, an ampersand, the entity name, and then a semi colon. The fifth column contains a description of the character, and an occasional note. There are many ways to order character entities. For more information on how to use these entities in your Web pages, see HTML, XHTML, and CSS, Sixth Edition by Elizabeth Castro.
