Abstract

A Generalized Mechanism for Unicode Metadata

Steven Atkin - IBM Corporation & Ryan Stansifer - Florida Tech

Intended Audience: Software Engineer, Systems Analyst
Session Level: Intermediate

The many competing motivations for selecting codepoints in the Unicode standard threaten the supreme purpose of a character encoding: data. Digital data is immensely conve-nient because the advantages of its great simplicity outweigh the loses incurred by representing knowledge imperfectly. Increases in computing power permit us to begin recovering what has been left out. Yet the very richness of the collection of Unicode characters has made the interpretation of text more difficult. Algorithms and reports are necessary now to understand raw streams of Unicode characters.

We propose a general mechanism for conveying metadata within Unicode. The conceptual boundary between codepoints and text processing is sharpened. The approach is both flexi-ble and extendable. Furthermore, algorithms such as the bidi-rectional algorithm can be recast in such a way that they become detectable and reversible.
