You have to set a font which has the required glyphs but you can also use different fonts for both scripts and combine them.

I understand that the font was not set... tried with your example...

\definefallbackfamily [mainface] [ss] [Noto Sans Devanagari] [range={devanagari,devanagariextended}, features=devanagari-two]

\definefontfamily [mainface] [ss] [Noto Sans]

\setupbodyfont[mainface]

The easiest way to achieve that is:

and repeat the three other steps from my previous message.

Here they are:

1. Remove "/home/gour/opt/lmtx/tex/texmf-cache/luatex-cache/".

$ rm -rf /home/gour/opt/lmtx/tex/texmf-cache/luatex-cache

2. Run "mtxrun --generate".

3. Run "context t.tex"

I use the following t.tex \definefallbackfamily [mainface] [ss] [Noto Sans Devanagari] [range={devanagari,devanagariextended}, features=devanagari-two] \definefontfamily [mainface] [ss] [Noto Sans] \setupbodyfont[mainface] \starttext ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते । सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते ॥ ६२ ॥ dhyāyato viṣayān puṁsaḥ saṅgas teṣūpajāyate saṅgāt sañjāyate kāmaḥ kāmāt krodho ’bhijāyate \stoptext as sugested by Wofgang, but it fails: $ context t.tex mtxrun | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua' Do I need to setup some other envvar as it is suggested in the link posted by Wolfgang?

Can you spot the difference?

Ahh, you are right!

I don’t know about fish, but I guess even there a space is not a valid path separator.

Well, fish shell works a bit differently, but in this case problem is that OSFONTDIR is a variable like PATH... Otherwise: $ set TEST a b c # define TEST envvar as array $ echo $TEST a b c $ echo $TEST[2] # access 2nd member from the array b $ set -e TEST[2] # remove 2nd member from the array $ echo $TEST a c

BTW: For me on MacOS Mojave, installing in texmf-fonts is unreliable, while installing in one of the OSFONTDIRs works.

My problem was that I had luatex engine installed from before and didn't install required (regular) fonts, so after installing google-noto-sans-fonts package everything is fine now. :-) Thanks everyone for all your help!

Actually, the problem was that OSFONTDIR is like a $PATH variable, so I reset it as: set -g -x OSFONTDIR "/home/gour/.local/share/fonts:/usr/share/fonts"

but otherwise why do you use such unusual shell? Why not bash or zsh?

Because it's Friendly Interactive SHell requring minimum setup and providing almost the same features as e.g. zsh, even more. Take a look: https://fishshell.com/

As you see, its value is semicolon separated paths.

Yes, that was my mistake. :-(

You have a problem here (aside from broken formatting). The 'mtxrun' didn't find necessary files, take a look on last part of output.

Devanagari support was added a while ago. The layout engine was according to reports working for at least one other Indic script (Bengali, I think), but not for others (Oriya? Can’t remember). I wouldn’t expect a renderer for Devanagari to do a very good job on Tamil or Malayalam, for example.

Do Hindi or Urdu need hyphenation patterns?)

Hindi uses hyphenation, Urdu doesn’t. We have patterns for Hindi in TeX-Hyphen: https://github.com/hyphenation/tex-hyphen/tree/master/hyph-utf8/tex/generic/... Best, Arthur

I'm not sure what you mean. Devanagari is the main category that determines the kind of processing. Different languages have different details. So, already for many years there is support for a bunch of these languages and some time ago a few more were added. This is something that Kai Eigner and I work ok occasionally and Kai did most of the logic, looking at what uniscribe does. He does high quality typesetting jobs so you can bet that it works (or worked) for the scripts/language combinations that he's familiar with.
