Code of Chinese ideogram set for information interchange supplementary set 1 Subject content and scope of application
This standard specifies the basic graphic characters and their codes for information interchange of compact characters. This standard applies to information exchange between systems such as overall word processing, traditional Chinese learning and communication. 2 Reference standards
GB1988
GB2311
GB2312
3 Terminology
3.1 Basic set
Information processing Seven-bit coded character set for information interchange Information processing Seven-bit and eight-bit coded character set Code extension technology Chinese character coded character set for information interchange Basic set Chinese character 24×24 dot matrix font set for information interchange Character set specified in GB2312.
3.2 Supplementary set
The traditional Chinese character set corresponding to the basic set.
Simplified characters
Symmetry of "tight body characters", for the same Chinese character, simplified characters have fewer strokes than purple body characters. Traditional characters
Symmetry of "simplified characters", originally had more strokes, and after the simplification of Chinese characters, simplified characters have replaced the characters. 3.5 Variant characters
Characters with the same pronunciation and meaning but different shapes.
Graphic characters
Graphic character code table
Graphic character code table is shown in Table 1.
Blank positions
In the code table, all blank positions that are not filled with graphic characters are used as further standardized areas. 4.3 Types and quantities of graphic characters

4.3.10 Chinese Characters
There are 6866 Chinese characters, including 3755 first-level Chinese characters, 3008 second-level Chinese characters, and 103 supplementary Chinese characters. The classification and arrangement of Chinese characters are shown in Appendix B (Supplementary).
The relationship and differences between this standard and GB2312 are shown in Appendix C (Reference). 5 Coding
5.1 Double-byte encoding in seven-bit and eight-bit environments In this standard, any graphic character is represented by two bytes in a seven-bit environment, and each byte is represented by the seven-bit encoding in GB1988 and GB2311. Of the two bytes, the high-order byte in front is the first byte, and the low-order byte in the back is the second byte. Their positions in the seven-bit code table are 2/1~7/14 or 21~7E (hexadecimal), see Table 1. In the seven-bit environment, the escape sequence indicating the graphic character set represented by the double-byte encoding of this standard is: ESC2/42/8F, ESC2/42/9F, ESC2/42/10F and ESC2/42/11F. In the eight-bit environment, the escape sequence indicating the graphic character set represented by the double-byte encoding of this standard is: ESC02/402/8F, ESC02/402/9F, ESC02/402/10F and ESC02/402/11F. When used as the G1 set, the position of each byte in the GB2311 eight-bit code table is 10/01~15/14 or A1~FE (hexadecimal), see Table 1. Note: The value of the termination character F is yet to be determined.
5.2 Method of indicating the position of graphic characters in the code table The code table is divided into 94 zones vertically, and each zone is divided into 94 bits horizontally. The zones are numbered from 1 to 94 and are identified by the high-order byte: the bits are also numbered from 1 to 94 and are identified by the low-order byte. The position of any graphic character in the code table is identified by the zone number and the bit number. The zone number and the bit number are connected by a hyphen.
Example: Chinese character “响” is represented by 16-01,
Note: ① The corresponding relationship between the column number and the row number in the area code and bit number GB1988 is: Column number/row number
2/1~7/14
2 The corresponding relationship between the area code and bit number and the column number and row number in the GB2311 eight-bit code table is: Column number/row number 10/01~15/14
10/01~15/14
Column number (row number
corresponds to area code 1~94,
corresponds to bit number 1~94.
