Many thanks for your reply, Hans,
The following code shows the problem:
\startluacode
function document.addfunnyhyphen(tfmdata)
local underscore = utf.byte("_")
local char = tfmdata.characters[underscore]
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
%~ \definefontfamily[ornamenta][rm][TypographyTribute]
\definehyphenationfeatures[underscore][righthyphenchar="FE000]
\setuphyphenation[method=traditional]
\sethyphenationfeatures[strict]
\setupbodyfont[ornamenta]
\starttext
\hsize\zeropoint
{\sethyphenationfeatures[underscore]\tt pandoc}
A
\stoptext
If you uncomment the line with the font definition, font loading crashes
compilation. It only crashes with this font
(http://www.dafont.com/typographytribute.font) or FontAwesome
(http://www.fontawesome.io).
Both lack the underscore glyph. This causes the crash, since it works
fine if I replace the glyph with an existing glyph in the font.
Error message:
code.tex: ! LuaTeX fatal error error in error handling

Would it be possible that ConTeXt silently ignores that the font doesn’t
contain the glyph?
I think this might be a bug.
Many thanks for your help,
Pablo
