How to read this
- A Unicode code point is a name tag unique to each character. Different fonts, same number — still the same character.
- In HTML, the numeric form &#number; works everywhere. Named entities like ♥ read nicer but exist only for some characters.
- In CSS, use a backslash and hexadecimal: content: "\2764".
- If the character shows as a box, the copy did not fail — that font simply has no glyph for it. Another font will show it.
