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

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]

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
