Description

Jena-core and IRI currently depend on ICU4J for implementing Unicode support. Since ICU4J is rather heavyweight of which a rather small fraction is used, we should check if there is a way of implementing the functionality in an alternative way, either by using built-in (standard) Java classes, (ii) other libraries that are already dependencies, or (iii) in a completely alternative way. This is also supported by the fact that since relevant parts have been initially implemented, Unicode support has been considerably extended in Java, see http://java.sun.com/developer/technicalArticles/javase/i18n_enhance/.
