Detailed explanation-1: -ASCII defines 128 characters, as Unicode contains a repertoire of more than 120, 000 characters.
Detailed explanation-2: -One byte character sets can contain 256 characters. The current standard, though, is Unicode which uses two bytes to represent all characters in all writing systems in the world in a single set. The original ASCII was a 7 bit character set (128 possible characters) with no accented letters.
Detailed explanation-3: -Unicode contains more characters than ASCII.
Detailed explanation-4: -Q: How many characters are in Unicode? The short answer is that as of Version 15.0, the Unicode Standard contains 149, 186 characters. The long answer is rather more complicated, because of all the different kinds of characters that people might be interested in counting.
