The project described in this paper takes advantage of the 7 year experience of the Academia Sinica Institute of Information Science Document Processing Laboratory in Studying the missing character problem. It is intended to develop a packaging and processing system which is compatible with international standards for use in an internet or Windows environment. The initial design constraints were to use XML markup as part of a system to allow the viewing and processing of documents containing missing characters by any personal computer capable of running Windows 98, and using standard software such as Microsoft Word. It requires no modification of the user`s system or software, and provides facilities for sharing data between users. The project was funded by a grant from the Republic of China (Taiwan) Ministry of Education, and is expected to be further developed to run on a larger variety of systems.
