Can you point me to the code that is involved in creation of the
composition data, when the font back-end is xftfont? Specifically,
those portions of creating the composition data that depend on the
font features, since the same composition displays correctly for the
OP (and I guess for you as well) with DejaVu Sans Mono. I will then
try to see what changes were done there since 24.5.
Thanks.
