The complete unicode character set runs to over 90,000 entries.
Extended Ascii Characters
At one time there were many versions of the extended ASCII set (128-255), used to provide (limited) foreign language and graphics support, below is the most popular set. These are not compatible with ISO or unicode and are no longer used in modern systems.
"Smart data structures and dumb code works a lot better than the other way around" - Eric S. Raymond
