Adding Unicode to a Legacy Code Page Client-Server Architecture

Carter Weiss and Atsushi Sakakibara - Information Builders, Inc.

Intended Audience: Software Engineer
Session Level: Advanced

Our presentation shows how we added Unicode support to Information Builders' legacy code page client-server architecture.

Information Builders' proprietary client-server RDBMS architecture (EDA) uses IBM mainframe, UNIX, and Windows NT hub servers to access a wide variety of legacy data types and SBCS/DBCS code pages. This is accomplished with the NLS API, an embedded facility that provides transcoding between any combination of supported code pages.

The heart of the presentation is a description of how we added Unicode UTF-8 and UTF-16 code pages to the set of supported legacy code pages, and the new functionality this provides to improve the product line. The enhancement now provides direct access to both legacy and Unicode data, and to third-party facilities in the Web environment.

We will also describe the complexities of supporting different browsers with our Java applet and servlet implementations.

We conclude with a live demonstration of WebFOCUS, our premier Web product. The demo shows concurrent servers on a laptop accessing, joining, and displaying multiple scripts and legacy code pages via Unicode in a Web server/browser environment.
