Unicode Collation and Normalization

Session Level: Intermediate, Advanced

The Unicode Collation Algorithm specifies a means for doing culturally correct ordering of Unicode strings. In this talk we present the basic concepts of the algorithm: how weights and levels are defined and how sort keys can be constructed from the default collation weight tables provided by the Unicode Consortium. A simple syntax for tailoring the default collation to enable correct ordering for any particular language or collection of languages is described and exemplified.

We also discuss the relationship between the Unicode Collation Algorithm and other emerging standards for international string ordering such as ISO 14651 and the European Ordering Rules.

For Normalization, UTR#15 will be discussed.
