Appendix D. (X)HTML Symbols and Characters

Appendix D. (X)HTML Symbols and Characters

As we discussed in Chapter 20, Symbols and Non-English Characters, you can add symbols and characters that don’t belong to your page’s encoding by inserting a character reference, that is, the symbol’s associated number, hexadecimal number, or name in the Unicode character set.

Since there are more than 65,000 characters in Unicode, printing out each one’s numeric or hexadecimal reference would require a book of its own, and be rather unwieldy to boot. Instead, you can consult Unicode’s site, (www.unicode.org) where the characters are neatly divided by language and theme.
