Those are currently largely handled long before the UAX14 implementation kicks in. Refinement white-space handling is dealt with before any TextLayoutManager is instantiated, so operates purely on the FOTree. > Perhaps setting break marks can be > folded into the whitespace handling loop. That's certainly a possibility. FTM, to deal with Manuel's particular problem, it may even suffice to add such break-marks only on FO boundaries (so as to avoid that the TextLM needs to look ahead (or back) at the next (or previous) FOText...)
