| 摘 要： | 编码字符集标准是计算机处理文字信息的基础,本文提出了编码字符集三元组抽象,对现有编码字符集标准进行了简单回顾和总结,深入剖析了影响巨大的ISO2022标准及其派生标准,对ISO2022编码机制应用于多语言环境的局限性进行了探讨,阐明了使用通用编码字符集UCS的必要性,并对其进行了分析。探讨了现有编码分类方法存在的问题,引入了一种对编码字符集以及实现方法进行分类的新方法,使用该方法对现有标准进行了归类;最后对汉字字符集相关的国家标准进行了分析评介。

| Abstract: | Coded character set standard are the bases of the computer text information processing.In this paper,a 3-turples model is proposed to descibe the coded character set.The existing code standards are reviewed and summarized.And the ISO 2022 and it's deriving standards are analyzed in detail;including the limitation of utilizing ISO 2022 in multilingual environment.Necessity of founding UCS(Universal Character Set) is presented,along with an outline analysis of UCS.After evaluating current classification methods of coded character set standards,a new method is produced with application in cataloguing existing standards.We close our paper with a brief analysis of important Chinese national standards on Han character set. |
