html

The following table gives the character entity reference, decimal character reference, and hexadecimal character reference for markup-significant and internationalization characters, as well as the rendering of each in your browser. Glyphs of the characters are available at the Unicode Consortium.

With the exception of HTML 2.0's ", &, <, and >, these entities are all new in HTML 4.0 and may not be supported by old browsers. Support in recent browsers is good.
