Introduction to inserting entities

Sometimes you want to insert special characters in your web pages. Because special characters do not appear on the keyboard, HTML supports a code number or name that corresponds to each special character. For example, consider the following examples of special characters, ®, ™, ©, etc. Listing 1 provides some of the common special characters used on a web page. See also a scripting tool for generating HTML code for special characters.

Listing 1 special characters and HTML codes
Code Name Code Description Symbol / Character
™ ™ Trademark symbol
© © Copyright symbol ©
® ® Registered trademark ®
&lt; &#60; Less than symbol <
&gt; &#62; Greater than symbol >
&amp; &#38; Ampersand &
&nbsp; &#160; Nonbreaking space  
&quot; &#34; double quote "

Because code names such as ™ and © are not recognized by older browser, you should instead consider using the code numbers. On the other hand, code names are easy to remember and use.
