What's the difference between ASCII and Unicode? -


can know exact difference between unicode , ascii?

ascii has total of 128 characters (256 in extended set).

is there size specification unicode characters?

ascii defines 128 characters, map numbers 0–127. unicode defines (less than) 221 characters, which, similarly, map numbers 0–221 (though not numbers assigned, , reserved).

unicode superset of ascii, , numbers 0–128 have same meaning in ascii have in unicode. example, number 65 means "latin capital 'a'".

because unicode characters don't fit 1 8-bit byte, there numerous ways of storing unicode characters in byte sequences, such utf-32 , utf-8.
