Hans,
I have the following sample (it includes Lua code for underscore
hyphenation):
\startluacode
function document.addfunnyhyphen(tfmdata)
local underscore = utf.byte("_")
local char = tfmdata.characters[underscore]
if not char then return end
tfmdata.characters[0xFE000] = {
width = 0,
height = 0,
depth = 0,
commands = {
{ "right", -char.width },
{ "down", char.depth },
{ "slot", 1, underscore },
}
}
end
utilities.sequencers.appendaction("aftercopyingcharacters",
"after","document.addfunnyhyphen")
\stopluacode
\definehyphenationfeatures
[underscore]
[righthyphenchar="FE000]
\setuphyphenation
[method=traditional]
\sethyphenationfeatures
[strict]
\definefontfamily[svb][rm][SV Basic Manual]
\setupbodyfont[svb]
\starttext
\hyphenatedword{legibility}
\stoptext
For some reason, the font gives the following error with the Lua code
(font can be downloaded from http://dl.dafont.com/dl/?f=sv_basic_manual):
lua error > lua error on line 33 in file svb.tex:
.../ctxbeta/tex/texmf-context/tex/context/base/font-ctx.lua:1194: bad
argument #9 to 'define' (number expected, got nil)
stack traceback:

33 >> \setupbodyfont[svb]
The weird thing here is that the Lua code isn’t applied to the
problematic font.
Is there a way to fix this strange interaction?
in that font the underscore has no depth, so:
commands = {
{ "right", -char.width },
{ "down", char.depth or 0 },
{ "slot", 1, underscore },
}
