Hi Wolfgang and Hans, I have the following sample: \setuppapersize[A5] \definefontfeature[default][default] [protrusion=quality, expansion=quality] \definefontfamily[mainface][rm][Source Serif Pro] \setupalign[hanging, hz] \setupbodyfont[mainface, 17pt] %~ \setupbodyfont[helvetica, 17pt] \starttext \input zapf \stoptext hz doesn’t work fine in MkXL, but it works fine in MkIV. I think the flow of characters is broken in MKXL. Some With TeX Gyre Heros (https://pdf.ousia.tk/mkiv-hz.pdf and https://pdf.ousia.tk/mkxl-hz.pdf): - "computer": line 5. - "basic": line 8. - "showing": line 10. With Source Serif Pro, also (https://pdf.ousia.tk/ssp-mkiv-hz.pdf and https://pdf.ousia.tk/ssp-mkxl-hz.pdf): - "publishing": line 2. - "about": line 4. - "between": line 10. I’m experiencing this wherever I use hz with MkXL. Sorry, but cannot the default values for quality font expansion be the same in MkIV and MkXL? Many thanks for your help, Pablo -- http://www.ousia.tk

Many thanks for your help, in lmtx there is more precise handling of edge cases (protrusion) that are ignored in mkiv ... so any difference that you observe can simply be a side effect of tex deciding otherwise (because these calculations do influence linebreaks)
anyway, you should use 'stretch' to because otherwise expansion and protrusion has not enough options to do better (the linebreak third pass that is) \setupalign[hanging, stretch, hz] Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

\setupalign[hanging, stretch, hz]
Many thanks for your reply, Hans. I’m afraid that "stretch" doesn’t make any difference with TeX Gyre Heros (https://pdf.ousia.tk/stretch-mkxl-hz.pdf) and it only corrected one problematic case with Source Serif Pro (https://pdf.ousia.tk/stretch-ssp-mkxl-hz.pdf). Sorry if I hadn’t expressed myself accurately before. The issue here isn’t having exactly the same output in both MkIV and MkXL. The real problem is that characters are misplaced in MkXL with hz enabled. I think this might be a bug. Many thanks for your help, Pablo -- http://www.ousia.tk

Many thanks for the new version, Hans. It works much better now. Dos the improvement come from the new LuaMetaTeX binary? Many thanks again, Pablo -- http://www.ousia.tk
