Chinese character code conversion method and equipment for cross-platform application of information system

Abstract

The invention discloses a Chinese character code conversion method and equipment for cross-platform application of an information system. The method comprises the following steps: generating a national standard coded full Chinese character text file containing all Chinese characters according to the byte length and code value range of Chinese character national standard codes; converting the national standard coded full Chinese character text file into a Unicode coded full Chinese character text file; generating a Chinese character national standard code and Unicode conversion intermediate mapping table according to the national standard code full Chinese character text file and the Unicode code full Chinese character text file; extracting Chinese characters from the character string to beconverted, and obtaining UTF-8 codes or national standard codes corresponding to the Chinese characters according to the Chinese character national standard code and Unicode code conversion intermediate mapping table and the Unicode code and UTF-8 code conversion rule. The method provided by the invention is simple and easy to implement, can provide a lightweight cross-platform universal Chinesecharacter code conversion means for information processing, especially an embedded terminal, and can support compatibility of a newly developed information system and Chinese information interaction of an existing system.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a Chinese character code conversion method and equipment. Background technique [0002] In the application of information system engineering in our country, in line with the development of the international era, most of the Chinese character encodings of various newly used tools and software adopt the globally shared Unicode character set, which can currently cover the symbols of the world's major languages and text. In terms of business fields such as command and control, network security, and public transportation, the Chinese character codes of the active information system include GB2312, GBK, and GB18030. In order to be compatible with the intertranslation and interoperability of existing systems, the new The developed information system will still face the requirement of Chinese character encoding conversion in the above-mentioned encoding form for quite a pe...

AI Technical Summary

Problems solved by technology

The library supports the interconversion between character set regional standards including the world's mainstream languages ​​and national standard encodings. However, for information processing with limited computing and processing resources, especially for embedded terminals, the resource occupation is a bit huge. And it is not conducive to general transplantation and transformation applied to various operating systems, especially localized operating systems
