Displaying And Imputing Characters Matching With GB18030 Character Set In VxWorks

Following the popularization of Computer Development and Application, the Real-time computer System becomes more and more important in the areas of Industry, Transportation, Scientific Research, Scientific Examination, and National Defence, etc. As the main Embedded Operation System, VxWorks has been used in comprehensive fields in our country, while it cannot manage characters with the length of four bytes. GB18030-2000 Coding Standard, which was issued by Chinese government on March 17, 2003, adopting a mixed way of single byte, two bytes, and four bytes to coding the Chinese Characters, and requiring that all domestic products of characters information processing must match with this standard.Based on VxWorks and using the intrinsic theory of characters displaying, this article constructs the date structure of Chinese characters and lattice information so that all characters of GB18030 Coding Standard can be identified and exchanged in VxWorks and can be exactly displayed in WindML.This article also introduces some basic concepts and principles of Chinese characters imputing, and particularly describes how to imputing characters matching with GB18030 Coding Standard in VxWorks.
