Entities for Symbols and Greek Letters

Glyphs of the characters are available at the Unicode Consortium. See in particular the Code Charts for Symbols and Punctuation, especially the following (pdf files; not an exhaustive list):

• Math Alphanumeric Symbols
• Letterlike Symbols
• Mathematical Operators

See also my own page of Latin-based letters and text symbols.

w3schools.com has a Complete HTML 4 Entity Reference.

Another complete list, perhaps more authoritative, but without the glyphs, is given by the World Wide Web Consortium (W3C).

The “left-” and “right-pointing angle brackets” “are deprecated and are strongly discouraged for mathematical use because of their canonical equivalence to CJK [Chinese Japanese Korean] punctuation,” according to Miscellaneous Technical (range 2300–23FF), called “Floors and Ceilings” on the index of character code charts.
