Hi Gerben,

I=E2=80=99m afraid they may be different issues: setting a = language and getting
the glyphs required for that = language.

See the following sample:

   \setupbodyfont[dejavu]
   \mainlanguage[russian]
=    \starttext
=    \hyphenatedword{%
=    =D0=9D=D0=B8=D0=BA=D0=BE=D0=BB=D0=B0=D0=B5=D0=B2=D0=B8=D1= =87
   typography
=    \en typography}
=    \stoptext

Since you set = the main language to Russian in the document, you would
have= to mark all English texts properly. I doubt this may be what you
intend.

The way to get a = fallback font would be (depending on which approach you
use)= \definefontfallback or \definefallbackfamily.

A sample of the second option would read:

\definefallbackfamily
=    [mainface]
   [ss]
   [FreeSans]
=    [preset=3Drange:cyrillic,
=     force=3Dyes]

In any = case,
http://www.pragma-ade.com/general/qrcs/setup-en.pdf#search=3D%2= 2definefontfallback%22
explains the syntax of the = first option (sorry, but I only use the
\definefontfamily = approach).

Just in case it helps,

Thank = you.

It could help if I = would understand ConTeXt better. The link gives me a grammar for a = command, but doesn=E2=80=99t 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=E2=80=99t 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=3Ddefault]

= \definefontsynonym [SansBold] = [file:Optima.ttc(Optima Bold)] = [features=3Ddefault]

= \definefontsynonym [SansItalic] = [file:Optima.ttc(Optima Italic)] = [features=3Ddefault]

= \definefontsynonym [SansBoldItalic] [file:Optima.ttc(Optima Bold = Italic)] [features=3Ddefault]

\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=3Drange:cyrillic,

= force=3Dyes]

\setupbodyfont = [optima]

The error = is:

fonts = > typescripts > unknown library = 'optima'

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 =E2=80=9CSyntax (autogenerated)=E2=80=9D = and =E2=80=9CSyntax entries on ConTeXtgarden? If they differ which one = should I take? If you tell me =E2=80=9Cpreset=3Drange:cyrillic and what = I find says "range=3Dcyrillic", 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=E2=80=99t 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=E2=80=99t this straightforward? I am = sorry, everybody is very helpful, but the frustration mounts = again.
