The following table gives the character entity reference, decimal character reference, and hexadecimal character reference for symbols and Greek letters, as well as the rendering of each in your browser. Glyphs of the characters are available at the Unicode Consortium.
Browser support for these entities is generally quite poor, but recent browsers support some of the character entity references and decimal character references.
