Hi Bruce and Hans !
Thank you very much for your answers, that helped me a lot.
In fact, though I would love to switch to ConTeXt one day, I am still
using LuaLaTeX — I am a slow learner and I know it will take me months
to be able to achieve what I need for my job with ConTeXt and can do
with LuaLaTeX and the Memoir class for the time being (despite sometimes
being irritated by LaTeX limitations or oddities).
keep in mind that context font handling and latex font handling can
differ (and not all that is possible in context is in the generic font
loader code); also, in (esp in lmtx) some solutions are not bound to fonts
I need the EB Garamond variable font for future jobs, but this font,
provided by Google Fonts, is such a mess : kerning problems, unusable
OpenType features that have to be rewritten from scratch, shifts in
glyphs table… For sure, the original font by Georg Duffner was much
better, but I need the variable version. Lots of fixing necessary, but
thanks to fonts.handlers.otf.addfeature I have almost succeeded to make
it a usable Garamond.
a probably more reliable solution is to 'remove bad stuff' from the
loaded font by running over the features and removing bad matches (which
is less sensitive for order)
Of course, it would be best to help Google improving this font, but I
don’t have time yet.
is that really a google font? afaik it doesn't originate there (unless
it among those things that google grabs - and at some point possible
discards)
The actual problem was with the italic ligatures "a_s", "e_s", "é_s",
"i_s" and "u_s", that should occur only at the end of words and not
everywhere. Instead of removing the unwanted ligatures, I chose another
way as soon as I understood how to fully use “current” to describe not
only a single glyph, but a string if necessary — for instance, current={
{ "a", "e", "eacute", "i", "u"}, {"s"} }
ok, good that you got it working
