Thank you.

It could help if I would understand ConTeXt better. The link gives me a grammar for a command, but doesn’t tell me what to put in.

I tried many, many different permutations, I tried everything I could find on ConTeXtgarden (but then, that also finds me stuff from 15 years ago that isn’t valid anymore), but no luck so far.

The last I tried was

\starttypescript [sans] [optima]
   \setups[font:fallback:sans]
   \definefontsynonym [Sans]           [file:Optima.ttc(Optima Regular)]     [features=default]
   \definefontsynonym [SansBold]       [file:Optima.ttc(Optima Bold)]        [features=default]
   \definefontsynonym [SansItalic]     [file:Optima.ttc(Optima Italic)]      [features=default]
   \definefontsynonym [SansBoldItalic] [file:Optima.ttc(Optima Bold Italic)] [features=default]
\stoptypescript

\definetypeface [optima] [ss] [sans] [optima] [default]
\definetypeface [optima] [rm] [serif] [optima] [default]
\definetypeface [optima] [tt] [mono] [modern] [default]
\definetypeface [optima] [mm] [math] [pagella] [default]

  \definefallbackfamily
    [optima]
    [ss]
    [file:Helvetica.ttc]
    [preset=range:cyrillic,
    force=yes]

\setupbodyfont [optima]

The error is:

fonts           > typescripts > unknown library 'optima'
open source     > level 3, order 6, name '/usr/local/context-osx-64/tex/texmf-context/tex/context/fonts/mkiv/type-imp-texgyre.mkiv'
close source    > level 3, order 6, name '/usr/local/context-osx-64/tex/texmf-context/tex/context/fonts/mkiv/type-imp-texgyre.mkiv'
selectfont      > the requested fallback font 'file:Helvetica.ttc' for typeface 'optima' style 'ss' was ignored because no files where found.


Which is weird because Optima.ttc is in the same directory and it is found.

I have a lot o difficulty understanding any of the documentation (as far as it is available for the subjects and commands I am lookng for).

For instance: what is the difference between the “Syntax (autogenerated)” and “Syntax entries on ConTeXtgarden? If they differ which one should I take? If you tell me “preset=range:cyrillic and what I find says "range=cyrillic", which one do I use ( in this case, changing did not help). There are just too many things that can be different for tial and error to be effective.

But anyway, even if I could understand it, I can’t find anything useful (that is: something that works or makes me try something that works) about font fallbacks. Spending hours of looking (losing a lot of sleep) and then having to bother the list again is very frustrating. Why isn’t this straightforward? I am sorry, everybody is very helpful, but the frustration mounts again.
