For copyright notices, or trademarks it is customary to include the appropriate signs:

SymbolEntityExample
Copyright sign©Copyright © 1999 W3C
Registered trademark®MagiCo ®
Trademark™Webfarer™

Note HTML 4.0 defines ™ for the trademark sign but this is not yet as widely supported as ™

There are a number of other entities you may find useful:

SymbolEntityExample
Less than&lt;<
Greater than&gt;>
Ampersand&amp;&
nonbreaking space&nbsp;
em dash&#8212;—
quotation mark&quot;"

And then, there are entities for accented characters and miscellaneous symbols in the Latin-1 character set:

&nbsp;&#160;Ð&ETH;&#208;
¡&iexcl;&#161;Ñ&Ntilde;&#209;
¢&cent;&#162;Ò&Ograve;&#210;

You can also use numeric character entities for the greek letters and mathematical symbols defined in Unicode. For more details, take a look at the list specified in the HTML 4 specification. Note that the entity names for these characters aren't recognized in Navigator 4, so you are recommended to stick to the numeric entities instead.
