The basic set includes a total of 6763 Chinese characters and 682 non-Chinese graphic characters. The entire character set is divided into 94 areas, each area has 94 bits. There is only one character in each location, so the location and location can be used to encode Chinese characters, which is called location code.
Add 2020H to the location code converted into hexadecimal to get the national standard code. Add the national standard code to 8080H to get the commonly used computer internal code. In 1995, the "Chinese Character Coding Extension Specification" (GBK) was promulgated. GBK is compatible with the internal code standard corresponding to the GB 2312-1980 national standard.
