Detailed explanation-1: -Unicode uses two encoding forms: 8-bit and 16-bit, based on the data type of the data that is being that is being encoded. The default encoding form is 16-bit, where each character is 16 bits (2 bytes) wide.
Detailed explanation-2: -Each character is encoded as 1 to 4 bytes. The first 128 Unicode code points are encoded as 1 byte in UTF-8. These code points are the same as those in ASCII CCSID 367. Any other character is encoded with more than 1 byte in UTF-8.
Detailed explanation-3: -Here are the original ASCII characters from 0-127. These are the same in UTF-8. There are 2048 possible 2-byte characters, but not all of them are valid and not all of the valid characters are used.
Detailed explanation-4: -Unicode groups all the characters, irrespective of the program, language or the platform and assigns a unique code value to them for processing. The initial version of Unicode used 16 bits for encoding each character. By using 2 bytes for the encode process, a total of 65, 536 characters only could be represented.
