The Chinese character international code is used as the "Chinese character exchange code" in the Chinese character processing system.

Related introduction:

Chinese character exchange code refers to the code standard used when different computer systems with Chinese character processing functions exchange Chinese character information. Since the promulgation of the national standard GB2312-80, my country has been using the national standard code stipulated in this standard as a unified Chinese character information exchange code.

GB2312-80 standard includes 6763 Chinese characters, which are divided into 3755 first-level Chinese characters and 3008 second-level Chinese characters according to their frequency of use. First-level Chinese characters are sorted by pinyin, and second-level Chinese characters are sorted by radicals. In addition, the standard also includes 682 punctuation marks, several Western letters, graphics, numbers and other symbols.

The area code and bit code of the area code are in decimal from 01 to 94, and the national standard code is in hexadecimal from 21H to 7EH (adding H after the number indicates that it is a hexadecimal number). The conversion relationship between the area code and the national standard code is: the area code and the bit code respectively add the decimal number 32. For example, if the word "国" is in row 25 and column 90 of the table, its location code is 2590 and the national standard code is 397AH.

Since GB2312-80 was a standard formulated in the 1980s, it is often insufficient in practical applications. Therefore, it is recommended that products that process text information adopt the newly promulgated GB18030 Chinese character encoding character set for information exchange. This standard is traditional and The simplified characters are all on the same platform, which can solve the problem of inconvenient character conversion between GB code and BIG 5 code among the three places across the Taiwan Strait.
