I was playing with the addfeature handler mentioned here
https://mailman.ntg.nl/pipermail/ntg-context/2016/083952.html and
run into a problem with ttc-fonts:
\starttext
\directlua{
fonts.handlers.otf.addfeature {
name = "oneb",
{
type = "substitution",
data = {
["1"] = "period",
},
},
"feature test",
}
}
\font\test= name:LatinModernRoman:+oneb \test
1234567890
\font\test= name:cambria:+oneb \test
1234567890
\stoptext
This gives:
.234567890
p234567890
So with latin modern it works fine, while with cambria the first
letter of the substituation is used.
The used fonts are:
filename=lmroman10-bold.otf filetype=otf format=otf
foundname=D:/context-minimals/context/tex/texmf/fonts/opentype/public/lm/lmroman10-bold.otf
usedmethod=database
filename=c:/windows/fonts/cambria.ttc format=ttc
foundname=c:/windows/fonts/cambria.ttc usedmethod=direct
(I have no idea why the bold version of lm is used, but I don't care
now)
Looking at the tma I see one difference between both fonts:
glyphs in cambria have no "name". A typical entry looks like this
[46]={
["boundingbox"]={ 109, 0, 311, 232 },
["index"]=484,
["unicode"]=46,
["width"]=420,
},
while with latin modern it looks like this:
[46]={
["boundingbox"]={ 81, 0, 237, 156 },
["index"]=88,
["name"]="period",
["unicode"]=46,
["width"]=319,
},
Is is normal that glyph of ttc-fonts have no name data? If yes how
should one do substituations in such fonts?

you can use the unicode number instead (unless i made a mistake)

I found the reason for that (side effect of utf conversion that takes
the first character) of 'period'.

i need to check it but some fonts have no sane glyph names (so we
discard them) and there is also an standard name set (so no need for
names then).
I uploaded a version that fixes the 'p' issue and falls back on agl
names as well.
