Hi there, there is a zero-cost font (not available for commercial works without previous permission) from Brill (http://www.brill.nl/news/brill-typeface). Standard ligatures such as fi and fl don't work: \usemodule[simplefonts] \definefontfeature[default][default][script=latn] \setmainfont[Brill] \starttext fi fl ff ffi ffl \stoptext The glyphs are defined (ff, fi, fl, ffi, ffl), but when I test ligatures with FontForge (Ctrl+K) these glyphs aren't used and single substitution lookups in different subtables are performed for the different ligatures (actually no ligatures are used). Sorry, my explanation isn't as accurate as it should. I'm not a font expert, but Substitutions can be browsed in FontForge selecting the glyph info (Ctrl+I). Is there something to report to the font designer or is there something not yet implemented in ConTeXt? Thanks for your help, Pablo -- http://www.oudeis.tk

The font seems to be using contextual substitution instead of regular ligatures (so the ligature glyphs are not really used, but alternate f’s and i’s etc. are used instead to give the same effect, quite helpful if you want to color only part of the ligature), so you may node to set mode to node: \definefontfeature[default][default][script=latn,mode=node] However, your example works here without any modifications (I added color commands just to showcase the usefulness of this approach). \usemodule[simplefonts] \definefontfeature[default][default][script=latn] \setmainfont[Brill] \def\r#1{\color[red]{#1}} \def\b#1{\color[blue]{#1}} \starttext \r{f}\b{i} \r{f}\b{l} \b{f}\r{f} \b{f}f\r{i} \r{f}\b{f}\r{l} \stoptext Regards, Khaled

However, your example works here without any modifications (I added color commands just to showcase the usefulness of this approach).
I'm afraid it doesn't work here either way (using ConTeXt stable from TL2011). Thanks for your help, Pablo -- http://www.oudeis.tk

ConTeXt in TeXLive is always out of date (for reasons beyond me), so you are better off using ConTeXt minimals distribution (it changed name several times lately and I'm sure what the current name is). Regards, Khaled

Thanks for the reply, Kahled. If I'm not wrong, TeXLive doesn't include beta software (this might be a reasonable choice). So ConTeXt standalone is the way to go (http://wiki.contextgarden.net/ConTeXt_Standalone). Pablo -- http://www.oudeis.tk

Here are two examples from an upcoming manual (about nasty font details ... quite some work so far from ready) \setupbodyfont[dejavu] \starttext \showotfcomposition{name:dejavuserif*default at 24pt}{1}{affiliation} \page \showotfcomposition{name:cambria*default at 24pt}{1}{affiliation} \stoptext Dejavu has real ligatures but cambria has alternate glyphs.
