In the position code of Chinese characters, the range of area code and position number is 0 1 to 94. The basic set of Chinese character coded character set for information interchange contains 6763 Chinese characters and 682 non-Chinese graphic characters. The whole character set is divided into 94 regions, each region has 94 bits. There is only one character in each position, so Chinese characters can be coded by position and orientation, which is called position code.

0 1-09 is a special symbol, 16-55 is a first-class Chinese character, sorted by pinyin, 56-87 is a second-class Chinese character, sorted by radicals/strokes, and 10- 15 and 88-94 are not coded.

Extended data:

Chinese characters and symbols form a 94×94 matrix. In this square matrix, each row is called a "region" and each column is called a "bit". Therefore, this square matrix actually constitutes a Chinese character set with 94 areas (area codes are 0. 1 to 94 respectively), and each area has 94 digits (digits are 0. 1 to 94 respectively). The area code and location number of Chinese characters are simply combined to form the "location code" of Chinese characters.

Location code query method:

1. Find Chinese characters with pinyin links. All Chinese characters are arranged in pinyin order. The pinyin of all Chinese characters is listed at the top of the table below. You just need to click on the pinyin you are looking for, and all the Chinese characters of this pinyin will be displayed on the screen. The number to the right of Chinese characters is the area code of Chinese characters. Click the "Back" link to the right of each pinyin, and the screen will quickly return to the top to find the next pinyin.

2. Check whether all Chinese characters are arranged in pinyin order. You just need to move the scroll bar on the right side of the browser window to find the Chinese characters you want. In the table, the number to the right of a Chinese character is the position code of the Chinese character.

For example, the word "Cheng" can be found in the table according to its pronunciation "Cheng", and then the word "Cheng" can be looked up at this position. After finding the word "Cheng", the number 1947 on the right side of the Chinese character is the Chinese character area code of "Cheng".

3. About the search of polyphonic words Because the positioning code is a Chinese character code, there is no duplicate code, so there is only one code for polyphonic words. When looking up polyphonic words, if you can't find them with one sound, you can look them up with another sound. For example, Chongqing's "heavy" is different from its "heavy" homonym, and the Chinese character "heavy" is coded according to the "middle" sound.

The national standard "Basic Set of Chinese Character Coded Character Sets for Information Interchange" was promulgated and implemented in May 198 1. The basic set specifies the basic graphic characters and their binary codes for Chinese character information exchange, and receives 6763 Chinese characters. It is suitable for information exchange between general Chinese character processing system and Chinese character communication system.

With the development of Chinese character information processing technology in China, the application scope of computers is constantly expanding, and it is urgent for departments that use more Chinese characters to continue to formulate national standards for auxiliary sets of Chinese character coded character sets for information exchange on the basis of the basic set.
