Detailed explanation-1: -The Unicode standard defines UTF-8, UTF-16 and UTF-32 . So, these use between 8 and 32 bits per character and has the advantage that it represents many more unique characters than ASCII because of the larger number of bits available to store a character code. It uses the same codes as ASCII up to 127.
Detailed explanation-2: -Unicode uses a 16-bit encoding scheme, which allows it to represent over 65, 000 different characters. This is significantly more than the 128 characters that can be represented using ASCII.
Detailed explanation-3: -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. In a properly engineered design, 16 bits per character are more than sufficient for this purpose.
Detailed explanation-4: -ASCII originally used seven bits to encode each character. This was later increased to eight with Extended ASCII to address the apparent inadequacy of the original. In contrast, Unicode uses a variable bit encoding program where you can choose between 32, 16, and 8-bit encodings.
Detailed explanation-5: -In fact, Unicode currently requires 21 bits to represent every possible character, which in turn means that we need 3 bytes. However, this will mean that all text content suddenly takes three times as much space to store, which isn’t ideal. As such, there are several different encodings we can use.
