特殊記号の表示

There are many different characters that you may wish to use on your webpage that do not appear on a standard keyboard. For example, you may wish to use a trademark symbol, or a copyright symbol in your page content. There are many, many different special characters available to display using a special type of ‘character reference’.

Special Characters are typically referred to using a name code, or a number code (also called a character entity or a numeric entity respectively) and there are three parts to both. Some characters may only have a numeric reference and not a character or name reference.

First a name code, or a number code begins with an ‘&’.
Secondly, the name or number that refers to the character.
Finally, a semicolon to denote the end of the character reference.
Here are some examples of a few different special characters:

Name Code Number Code Glyph Description

Name Code Glyph Description
™ ™ Trademark
© © © Copyright
« « « Left Angle Quote
→ → Rightward Arrow
♥ ♥ Black Heart Suit
¢ ¢ ¢ Cent Sign

Don't forget that as time goes on, new entities are added and some of these may not be understood by all browsers.
