Character encoding (English: Character encoding), also known as character set code, is to encode characters in a character set into an object in a specified set (for example: bit pattern, natural number sequence, 8-bit group or electric pulse) so that the text can be in the computer Storage and delivery through communication networks. Common examples include encoding the Latin alphabet into Morse code and ASCII. Among them, ASCII numbers letters, numbers and other symbols, and uses 7-bit binary to represent this integer. An extended bit is usually used to facilitate storage in 1 byte. In the early days of computer technology development, character sets such as ASCII (1963) and EBCDIC (1964) gradually became standards. But the limitations of these character sets quickly became apparent, so people developed many methods to extend them. The requirement for supporting writing systems including the East Asian CJK character family can support a larger number of characters, and a system rather than a temporary method is needed to achieve the encoding of these characters
