I'm still a bit at a loss on how one goes about correctly specifying the variants in \definefontfamily using the default form given in the wiki. Usually adding "* Light", etc. is sufficient (see commented line using Junction font). (As an aside, is it also possible to combine \sc\bf? I haven't been able to figure that out). My application is using the (free) Andada font family, and I need to point the smallcaps style to the correct font (https://www.fontsquirrel.com/fonts/andada). In the following MWE I tried the following without success: 1. [sc=* SC Regular] 2. [sc=Andada SC Regular] 3. [sc=* SC-Regular] 4. [sc=Andada SC-Regular] All give the following (or similar) error to stdout: ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:121: attempt to index local 'file' (a nil value) stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:121: in function 'selectfont_savefile' ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:151: in function <...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:142> ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:526: in function 'registerfiles' ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:567: in function 'action1' [string "local function scan1()..."]:55: in function <[string "local function scan1()..."]:42> 1 \definefontfamily[mainface][rm][Latin Modern] 2 >> \definefontfamily[mainface][rm][Andada][sc=Andada SC Regular] I end up finally settling on the form using the explicit file: [sc=file:AndadaSC-Regular.otf], which does work. But I really would like to understand how the first form as given in the wiki should be used properly? What patterns should I be looking for? An output of 'strings' on the font .otf file yields: "... with Reserved Font Name 'Andada'Andada SCRegular" "AndadaSC-Regular" advTHANKSance.
