Hi Gerben,
I’m 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{% Николаевич 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=range:cyrillic, force=yes]
In any case, http://www.pragma-ade.com/general/qrcs/setup-en.pdf#search=%22definefontfall... 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’t tell me what to put in.
Prepare a (small) example, for example.
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.
Note that log says about "Helvetica.ttc" not "Optima.ttc". Why you mention it is it a typo and you mean "Helvetica.ttc"? I'm not sure how context searches for fonts, but when I plainly use "standard" locations for fonts, for example OSFONTDIR variable, it could find and use requested font.
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.
I couldn't help here because I understand better the LaTeX font mechanism than ConTeXt one but I don't use ConTeXt as often as LaTeX. If I understand correctly, fallback mechanism allows to use some "main" font for most of letters in a document, for example, for Latin letters and use another font, if some letters are missing from "main" one. The "missing" is based on letters codes, see "range" above. Your original question is a bit unclear to me. Do you want typeset document with Cyrillic letters, for example Russian text or just want to include some words using Cyrillic (Russian) letters? The former assumes that you will use \mainlanguage[ru] and appropriate font with Cyrillic glyphs, while for the latter you need only the font. I'm not a Mac OS user neither I have Optima nor Helvetica fonts, but Computer Modern Unicode (OTF) and OldStandard (OTF) have both Cyrillic and Latin letters (OldStandard doesn't have support "out of box" in context while Computer Modern Unicode has) so I made two small examples (well, the first example not so small, sometimes I prepare example not only for others but for myself too) which show both uses. Both fonts can be found on ctan: https://ctan.org/pkg/cm-unicode and https://ctan.org/pkg/oldstandard.
