Hi Hans,

Which makes me wonder: are there specific additional features that one
would like to see in context (mkiv only of course) with respect to
font support?
This may be beyond the scope of your current plans, but worth
considering: It would be nice to have a mechanism where we can
override/add opentype gsub and gpos features. Early on in the history of
luatex we once had a mechanism that did this using FontForge's version
of Adobe Feature Files. From what I understand, the AFF syntax is
finally mature and supports all lookup types:
http://www.adobe.com/devnet/opentype/afdko/topic_feature_file_syntax.html
Or maybe we have our own syntax in lua, goodies etc. Anyway, a way to
control/override opentype gsub and gpos behavior would be interesting.
Even if a total controller is too ambitious/unwieldy, just being able to
do a few basic gsub/gpos tricks may be useful for, e.g., bugs in the font.
Anyway, something to think about.
Best wishes
Idris
Hi Idris and Hans,
this is a great idea. Is this not available any longer in current
luatex? The fontspec (xelatex+lualatex) manual lists this as a luatex
only feature (I’ve used it once some time ago). I know a lot of fonts
and other problems that could be fixed this way. I’d prefer to stay with
the AFF syntax which is well established.
Best regards,
Georg
