摘　　要：目前应用较为广泛的复杂文本布局引擎有微软的Uniscribe和IBM的ICU.通过对复杂文本布局引擎机制的研究,结合开放源码的复杂文本布局引擎(如ICU布局引擎)代码分析,可以在其中加入该引擎尚未支持的复杂文本(如中国少数民族语言蒙、藏、维)的实现模块,并以此开发出基于OpenOffice的用于中国少数民族地区的办公套件.Two types of complex text layout engine are widely used today： one is Microsoft＇ s Uniscribe and the other is IBM＇ s ICU. By studying its mechanism and analyzing the source code of a certain type of open source complex layout engine （such as ICU layout engine）, we can add new code models which support new complex scripts （such as China＇s minority languages of Mongolian, Tibetan, and Uigur） into the complex text layout engine and develop a version of office software based on OpenOffiee for China＇ s minority languages. This paper firstly explains what the complex scripts and complex text are; then it analyzes the mechanism of the complex text layout engine; lastly it illustrates how to apply the complex layout engine to develop a version of office software based on OpenOffice suitable for China＇s minority languages.
