Detailed explanation-1: -Unicode is intended to address the need for a workable, reliable world text encoding. Unicode could be roughly described as “wide-body ASCII” that has been stretched to 16 bits to encompass the characters of all the world’s living languages.
Detailed explanation-2: -Unicode is a universal character encoding standard. This standard includes roughly 100000 characters to represent characters of different languages. While ASCII uses only 1 byte the Unicode uses 4 bytes to represent characters. Hence, it provides a very wide variety of encoding.
Detailed explanation-3: -The Unicode Standard makes it possible to access and manipulate characters by unique numbers (that is, their Unicode code points) and use older encodings only for input and output, if at all.
