Win2K and XP support UniCode, a new character encoding scheme that 
utilizes TWO bytes per character instead of one byte classic ASCII 
codes.   This allows 65,000-plus unique codes to represent characters in 
a font instead of 255.   .UniCode now assigns a unique unchanging 
numeric value to EVERY SYMBOL in EVERY LANGUAGE known to man, including 
dead languages such as Egyptian hieroglyphics and Aramaic.  This makes 
possible single fonts that can support multiple languages. (Most of the 
standard Win 2K and XP fonts like Arial, Times and Courier are now 
subsets of Unicode that support all languages written in Latin 
characters {English, the West European languages, the East European 
Slavic languages, the Nordic languages and Vietnamese] + Greek +  Hebrew 
+ Arabic + Russian.)   
     Installing MS Office on your machine installs a nearly FULL Unicode 
font, "Arial Unicode".  This font, which supports virtually every 
language currently in use in the world, including thousands and 
thousands of Chinese and Japanese characters, has 30,000+ characters in 
a single 25 Megabyte font file.

As a result of the UniCode support in Win2K and XP,   the ALT-numeric 
pad entries of classic ASCII characters (which occupy the first 128 
slots in the UniCode numbering scheme)  now need to be done with FOUR 
digits instead of three.   For ASCII values, the leading digit is always 
zero.


Thus the KISS escape routine has to be typed as ALT-0192,  ALT-0255, 
ALT-0192 .
