计算机与不同用户的交互通常必须实现通过多种文字信息的输入/输出以实现,因此操作系统对多种文字的支持程度是其功能性的一个衡量标准。各种文字特征的巨大差异导致现代操作系统的文字处理实现非常复杂。本文总结了操作系统文字处理的范围与内容,包括文本输入与存储,文本处理以及用户交互处理;归纳了通用的文字处理模型和可能采取的技术途径及其优缺点;分析了常用操作系统的文字处理实现;最后展望了文字处理仍面临的挑战。
Abstract
The implementation of multilingual text I/O is essential for computers to interact with all sorts of users in the world. One of the most important functionalities for a computer is , how and to which extent its operating system supports languages with multi-scripts. Owing to considerable differences amongst scripts , multilingual text processing in an a global operating system is very complicated. In this paper , firstly , the scope and the content of multilingual text processing are defined , including text input , store , processing and interactions in an internationalized manner. Secondly , models for text processing are outlined ; several technical solutions are discussed ; the pros and cons are listed. Thirdly , technical features of text processing implemented by current operating systems are analyzed. Finally , some challenges in the realm of internationalized text processing are presented.
