David, Thanks for the response. I did look at LineBreakMeasurer, but in looks as though the most powerful layout mechanism available is Font.layoutGlyphVector. The docs say:
"Returns a new GlyphVector object, performing full layout of the text if possible. Full layout is required for complex text, such as Arabic or Hindi." It was that flexibility and power I was after. You have to do your own Bidi which is a complicationg factor, but you get everything else, as far as I can tell. I'm using AttributedString as well, with subclasses of AttributedCharacterIterator.Attribute for hyphenation markers and character replacement graphics. Full layout is an expensive process, so I would like to be able to work off the GlyphVectors I have, if possible, to retrieve the broken lines.
