Dear list, I am trying to access extra kerning that I have defined using fonts.handlers.otf.addfeature. Even though I query the kerning from within a paragraph where the kerning is evidently applied I can't seem to get the value stored earlier, see the comment in the MWE. What am I doing wrong?
Cheers, Henri --- \startluacode fonts.handlers.otf.addfeature { name = "ktest", type = "kern", data = { ["t"] = { ["e"] = 500 }, } } \stopluacode \definefontfeature[ktest][ktest=yes] \definefont[1][Serif*ktest] \starttext \1 test \ctxlua{ local fnt = font.current() local tfmdata = fonts.hashes.identifiers[fnt] local t = string.byte("t") local e = string.byte("e") local kern = fonts.handlers.otf.getkern(tfmdata,t,e) context(kern) % 0 instead of 500.
