I need the lua code to have underscore hyphenation in type commands. And I need two extra \definehyphenationfeatures and \sethyphenationfeatures to invoke it.
Have I hit a bug or what am I missing?
I don't know as i see nothing at all with that code .. this is more fun:
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: !

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 -- http://www.ousia.tk
