Hi,
with EB Garamond Italic and contextual ligatures I get a weird
duplicate “s” for the pairing “us”:
·······································································
\starttext
\definefontfeature[default][default][clig=yes]
\definedfont[ebgaramond12italic*default at 42pt]
%definedfont[ebgaramond08italic*default at 42pt]
foo us bar ss fi ffi ffl fj\endgraf
Thus, I came to the conclusion ...
\stoptext
·······································································
Occurs in Context and Luatex-Fonts, not only on my machine. Can
some confirm this? Also I’d like to know if that’s a bug in the
font or the font loader.
Thanks
Philipp

could be a bug, probably the first time we run into such a case
(specific kind of chains subs)

you can test with
local function s_hashed(t,cache)
if t then
local ht = { }
local tf = t[1]
for i=1,#tf do
ht[i] = { [tf[i]] = true }
end
return ht
else
return nil
end
end
in font-otf.lua (you need to delete the cached font) - i wonder what the
original test font was (might as break that one)

Thanks, applied! No noticable breakage.
