摘　　要：Unicode标准中的非BMP平面字符多用于古籍研究或者少数民族语言文字,由于这些字符的使用面特别窄,多数软件系统包括办公软件都不支持对这些字符的处理。本文以开源办公套件OpenOffice.org为基础,分析了它对非BMP平面支持的现状,然后着重探讨了实现对非BMP平面字符的全面支持所需要解决的一系列问题,并分别给出了合理的改进方案,最后以CJK和藏文为例展示了改进后的效果。Non-BMP characters in the Unicode Standard are mostly used in the study of ancient books （e. g. CJK Ext-B）, or in representing the scripts of minorities （e. g. Tibetan Ext-B）. Thus, their users are rare, and lots of software, including software for office, fails to support them. Based on OpenOffice. org, this paper firstly analyses its state of arts of supporting non-BMP characters. Then several key questions, which should be taken into account while supporting non-BMP characters, are discussed. Furthermore, we provide reasonable solutions to each question mentioned above. Finally some samples in CJK and Tibetan are given to show the effects of OpenOffice. org after being enhanced.
