摘　　要：国内藏文软件开发普遍使用的是基于垂直预组合字符的实现方案,但是缺乏统一的编码标准。藏文编码字符集扩充集的推出,对于国内藏文软件的标准化、国际化具有重要意义。本文通过分析ISO/IEC 10646藏文编码字符集基本集、藏文编码字符集扩充集国家标准,区分它们描述字丁的差异,分析由编码方案所导致的实现上的关键问题。最后,针对藏文扩充集B的特殊性,提出并实现了基于Linux国际化架构下支持藏文扩充集标准的解决方案。There lacks corresponding coded character standards which regulate the commonly used BrdaRten characters in software development. The newly shipped National standards, ＂Information technology--Tibetan coded character set--Extension A＂ and ＂Information technology-Tibetan coded character set-Extension B＂, are of great importance to the standardization and globalization of software development in China. In this paper, the encoding methods adopted by Tibetan character set defined in ISO/IEC 10646 and Tibetan coded character set extension A/B are compared; critical problems for implementations are analyzed. Finally, for the special characteristics of Tibetan coded character set--Extension B, based on Linux I18N architecture, a reasonable solution is proposed to thoroughly support the newly shipped National standards.
