Chinese coded character set for information exchange
Basic set
1. Scope of application
GB2312-80||tt| |This standard specifies the basic graphic characters and their binary encoding representation for Chinese character information exchange. It is suitable for information exchange between general Chinese character processing, Chinese character communication and other systems. 2. Main relevant standards
2.1GB1988-80 "Seven-bit coded character set for information processing and exchange" 2.2GB2311-80 "Expansion method of seven-bit coded character set for information processing and exchange" 3. Term meaning|| tt||3.1 bit group: An ordered set of binary bits representing a character. 3.2 Code, coded character set: establish a character set with a clear set of rules; and establish a one-to-one correspondence between the characters in the character set and their bit groups.
3.3 bytes: A string of binary bits processed as a unit. 3.4 Graphic character: It is a character different from control characters. Usually this character has a visual graphic, which can be visually expressed by handwriting, printing or display. 3.5 Escape sequence: A bit string used to expand the code. It consists of two or more byte groups, the first of which is the escape character (ESC).
3.6 Specify: In some pre-established character sets, use a prescribed method to indicate a specific character set. 3.7 Call: Make the specified encoding character set available for use. 3.8 means
(a) uses the specified bit group according to the meaning of the characters in the specified and called character set. (b) Use escape sequences in their supplementary control function sense. 4. Graphic characters
4.1 Graphic character code table
The graphic character code table is shown in Table 1.
4.2 Blank positions
In the code table, any blank position that is not filled with graphic characters will be used as a further standardized area. 4.3 Types and quantities of graphic characters
This standard includes general symbols, serial numbers, numbers, Latin letters, Japanese kana, Greek letters, Russian letters, Chinese pinyin symbols, Chinese phonetic letters, Chinese characters, etc., a total of 7445 graphics character. 4.3.1 There are 202 general symbols. These include intervals, punctuation marks, operation symbols, unit symbols and tabulation symbols. National standards

GB2312—80
4.3.2 serial number 60 pieces. Among them, there are 20 in total from 1 to 20., 20 in total from (1) to (20), 10 in total from ① to @, and 10 in total from (1) to (10).
4.3.3 Numbers 22. Among them, there are 10 numbers from 0 to 9, and 12 numbers from I to 1. 4.3.4 Latin letters There are 52 Latin letters. Among them, there are 26 uppercase letters A**Z and 26 lowercase letters a..Z. 4.3.5 Japanese Kana There are 169 Japanese Kana. Among them, there are 83 hiragana (including lowercase kana with voiced, semi-voiced, kobe, and auspicious sounds), and 86 katakana (including lowercase kana with voiced, semi-voiced, and aura, auspicious sounds, etc.). 4.3.6 Greek letters There are 48 Greek letters. Among them, there are 24 uppercase letters A****9Q and **024 lowercase letters. The Russian alphabet has 66 letters. Among them, there are 33 uppercase letters A.. and 33 lowercase letters a*. 4.3.7
Chinese Pinyin symbols There are 26 Chinese Pinyin symbols (including letters with tone symbols and other symbols). 4.3.8
4.3.9 Chinese phonetic alphabet There are 37 Chinese phonetic alphabet spoons. 4.3.10 Chinese characters There are 6763 Chinese characters, divided into two levels. There are 3755 Chinese characters in the first level and 3008 Chinese characters in the second level. See Appendix 2 for the classification and arrangement of Chinese characters.
5. Encoding
5.1 encoding representation This standard uses two bytes to represent any graphic character, and each byte is represented by the seven-bit encoding in GB1988-80 and GB2311-80 . The first byte of the two bytes is the first byte, and the latter byte is the second byte. 5.2 Specification and calling in a seven-bit coded character set, specified with the three-character escape sequence ESC2/44/1, and called by a shift-in character (SI).
5.3 Representation method of the position of graphic characters in the code table The code table is divided into 94 areas, each area has 94 bits. The area numbers range from 1 to 94, identified by the first byte; the bit numbers also range from 1 to 94, identified by the second byte. The position of any graphic character in the code table is identified by its area code and bit number. The area code and location number are connected with a hyphen. Example: The Chinese character "" is represented by 16--01.
Note: The area code and bit number have the following correspondence with the column number and row number in GB1988--80: column number/line number
