HTML Character Entities

What are the codes for the HTML special characters I can use in a SSI Web survey?

Below is a list of the 252 allowed entities in HTML 4 as outlined in section 24 of the official HTML 4 specifications, published by the W3C. The first line displays the symbol, the second line displays the named HTML character entity which may not be supported by all browsers, and the third line is the alternative numeric reference entity that should work in just about every browser.
