It depends on what symbols you are after.
Some symbols and characters have specific html code e.g.
html ----------- symbol
& q u o t ; ----------- "
& # 3 8 ; ----------- &
& c op y ; ----------- ©
& r e g ; ----------- ®
& f r a c 3 4 ; ----------- ¾
& s p a d e s ; ----------- ?
Do a search in Google for html codes for symbols etc
(I added extra space between code to stop it displaying symbol)
