Character Entities
Table B.1 contains the possible numeric and character entities for the ISO-Latin-1 (ISO8859-1)
character set Where possible, the character is shown
Note
Not all browsers can display all characters, and some browsers may even display different
characters from those that appear in the table Newer browsers seem to have a better track
record for handling character entities, but be sure and test your HTML files extensively with
multiple browsers if you intend to use these entities
