Explanation:
Detailed explanation-1: -The major disadvantage of ASCII is that it can represent only 256 different characters as it can use only 8 bits. ASCII cannot be used to encode the many types of characters found around the world. Unicode was extended further to UTF-16 and UTF-32 to encode the various types of 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.
