Infinity symbol with HTML

Question

How can I display an infinity symbol (like the one in the picture) using HTML?

Answer 1

You can use the following:

• literal: ∞ (if the encoding you use can encode it — UTF-8 can, for example)
• character reference: ∞ (decimal), ∞ (hexadecimal)
• entity reference: ∞

But whether it is displayed correctly does also depend on the font the text is displayed with.
