汉字区位表（Chinese location table） (1) location codes are first converted into sixteen hexadecimal numbers (2) (location code sixteen hexadecimal) 2020H = GB code; (3) GB code 8080H = machine code The city code and the code is a decimal number converted into machine code, to the city code and the code are converted to 16 hexadecimal code 1D and 0D. 1D0D+A0A0=BDAD. Why add A0A0? This is the principle of conversion. Specific process 1. location code (decimal) converted into location code (sixteen hexadecimal). Here you want to change the first two bits to sixteen decimal, and then the two to the sixteen. For example, the location code of a Chinese character is 2913, so that 29 is converted to 16 decimal number 1D, then the bit code 13 is converted to 16, the hexadecimal number is 0D, and the sixteen decimal number 1D0D is obtained. 2. = international code area code (sixteen m) 2020H For example, 1D0DH+2020H=3D2DH gets GB code GB2312 3. machine code = International Code 8080H Chinese characters Machine code is 3D2DH+8080H=BDADH Sixteen hexadecimal B0A1 The first location code corresponding to the decimal to hexadecimal sixteen, then add 2020H into the GB code, finally added in 8080H into machine code, specific process: 1.16-10H 01-01H 1601=1001H 2.1001H+2020H=3021H 3.3021H+8080H=B0A1H Chinese characters are made up of two bytes. Such as GB2312-80. Each Chinese character and symbol is represented by two bytes. The first byte is called high byte (also called zone byte), and the second byte is called low byte (also called bit byte). High byte uses the 0xA1-0xF7 (adds the 01-87 area code to 0xA0), and the low byte uses the 0xA1-0xFE (01-94 plus 0xA0). Since the first Chinese character starts from the 16 area, the high byte range of the Chinese character area is 0xB0-0xF7, and the low byte range is 0xA1-0xFE, and the occupied code bit is 72*94=6768. 5 of these seats are D7FA-D7FE. For example, ah is stored in most programs in two bytes, 0xB0 (first byte), and 0xA1 (second bytes)
