传统的以字节为对象的文本处理方法在今天越来越显出它的弊端。本文提出的基于变长码的面向字符的文本处理方法, 在统一编码的基础上, 将逻辑字符与它的存储方式独立开来, 并以此为单位进行文本处理。这种方式可以有效地解决汉字等多字节字符集的编辑、显示、检索的不便, 还可使字符集的容量无限扩充。本文陈述了变长码的概念与面向字符的文本处理方法的基本思想, 并以汉字处理为例给出了几个层次的实现方法。

The traditional way of text process causes more and problems today. In this paper , we will put forword a new mothod called COTP (character oriented Text Process) which is to unify the codes in the world and then separate the logical character from its storage format , and to process text with such characters as units. This method can bring convenience to both programmers and users in editing , displaying and searchng texts in Chinese and other languages. It can also make the dimensionof character set infinite. We will first explain the VLC and COTP. and then discribe how to take advantage of COTP in several different ways.
