Thorsten Möller commented on JENA-177:
--------------------------------------
BTW, ICU4J is modularized, meaning that it provides options to build smaller
ICU4J modules, see http://userguide.icu-project.org/packaging-icu4j. Seems that
the "Normalizer" module would be sufficient, provided that DNS name
normalization is moved to java.net.IDN available since JDK1.6 (as done by the
patch).
This would be another option to reduce the overhead in case entirely factoring
out ICU4J is not possible at the moment. Unfortunately, I'm not aware of a
Maven repository that already contains ICU4J modules. Is there an ASF Maven
repository, and would it be an option to upload an ICU4J module?

> 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 (i) 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
