ASCII vs UNICODE

ASCII

American Standard Code for Information Interchange

7 bit code is 128 characters

Extended 8 bit ascii -  256 characters

 

UNICODE

16 bit -  65,536 characters (2^16)

 

+ allows us to represent more world languages like Chinese, Japanese etc

 

-        It takes more memory per character

UNICODE has ASCII included in it at the exact same places i.e 65 in ASCII and 65 in UNICODE give A!!!!!
