What Unicode character do you use in your website? (instead of image icons)

Question

I am looking for character which could replace image icon, for example like ✘ (xmark) and ✔ (tick), maybe some symbol to \"draft\" or \"new message\"?

EDIT:

Answer 1

http://unicode-table.com/ is great too but for some unicodes designed for web design icons, i recommend : http://kudakurage.com/ligature_symbols/.
