Special Characters.
Back in ye olden days i was a big fan of using alt codes to produce special characters that built pseudo-GUIs for my PASCAL programs but i’d never twigged that many of these characters would be available in HTML too. Despite being a regular user of and © i’d never thought that classics like ♦ ♣ ♥ ♠ would be there too. Yes, sometimes i am very slow.
Anyway, here’s a very big list of the special characters available in HTML.
Enjoy. ☂
