In general the idea is similar to how this is handled in databases, you can index collation keys into a sort field at analysis time, then you just do a standard solr sort. However, I am not sure if your JRE provides a "haw" Locale for the Hawaiian language. Because of this, its probably better to use the ICU collation integration (http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.ICUCollationKeyFilterFactory), because ICU definitely supports this locale and has collation rules for it.
