藏文综合编码方案的研究与实现

A research and implement of Tibetan Comprehensive Coding Method

目前，藏文处理系统中普遍存在着外字困扰问题，本文首次实现了彻底排除外、字的全新编码方案──综合编码方案，它由通行编码方案和外字编码方案两部分组成。通行编码方案按双字节１１模式编码，外字编码方案采用组合叠加编码。文中对外字组合叠加编码方案作了深入地研究，提出了外字运算符、外字描述和顺序输入叠加输出等概念．设计了自动造字算法和程序，解决了外字处理的一系列技术障碍，并在Ｓｕｐｅｒ－ＣＣＤＯＳ汉字系统ＷＰＳ５．０版本上实现了藏文综合编码方案，其方法可引伸到其它藏文处理系统。

AbstractMany Tibetan information processing systems are puzzled by the problem of Tibetan new characters at the moment. A new Coding method for Tibetan characters──comprehensive coding method (CCM) is put forward for the first time in this paper, which slovesthe problem of Tibetan new characters thoroughly. CCM consists of the Normal Coding Method (NCM) and the Tibetan new character coding method (TNCCM). NCM is 2 bytes 11 mode coding, and TNCCM is combined coding. In this paper, TNCCM is discussed thoroughly,the concepts of 'new character operator'、'new character description' and 'horizontal input in sequence but vertical combined output' are proposed, making character algorithms and programs are designed, and a series of technical barriers of new character processing are broken down. At last TNCCM has been realized on Super-CCDOS and WPS 5. 0 successfully. This method can extend to other Tibetan information processing systems.
