My online charmap of HTML character entities24 Aug 2004
Geeky as hell, but I need it quite often, and what better place to put it but here: the list of 250+ HTML character entities.
Handy if you would want to write σ = ¾ • ∑ ƒ(χ²) – or your name like “πετερ“
UPDATE: now an even more complete overview can be found on Online Character map. Convert your own text to HTML-encoded with HTML encode.
