HTML Character Reference

Symbols, Mathematical Symbols and Greek Letters

The following named character entities are defined by HTML 4.0 and XHTML 1.0. They are simply a few selected UCS characters that have been given a name as well as having a number, so they'll probably be big with Prisoner fans as well as mathematicians. Note especially the trademark symbol (™ or ™) which should be used instead of the non-standard Windows character with code position 153.
