This gives:

.234567890
p234567890

So with latin modern it works fine, while with cambria the first
letter of the substituation is used.


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



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?


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.

["1"] = 46 works, but as names are easier to handle I'm still
interested to know why cambria doesn't have them.
