There actually is no such thing as "extended ASCII" -- there is a whole 
series of many different "extended ASCIIs". If you look at the encodings 
available in (for example) Thunderbird, many of the ISO-8859-* and 
Windows-* encodings are "extended ASCII" in the sense that they extend 
ASCII to include bytes 128-255. Unfortunately they all extend ASCII in a 
different way (hence they are different encodings).
