Proper ligatures in Malayalam
Hi, I tried to make a document in Malayalam, an Indian language. However, the ligatures don't form as expected. A minimal example is \mainlanguage[ml] \definefontfamily [malayalam] [ss] [Rachana] [features=malayalam-one] \definefontfeature[default] [mode=node,kern=yes, liga=yes,tlig=yes, ccmp=yes,language=dflt, protrusion=quality, expansion=quality] \setupbodyfont [malayalam] \starttext അദ്ധ്യായം \stoptext What setting am I missing? The expected form is show in libre office with the same text and font, attached as an image The sequence of Malayalam characters used is U+0D05 U+0D26 U+0D4D U+0D27 U+0D4DU+0D2F U+0D3E U+0D2F U+0D02 Thanks, ajith

Hi Ajith, I don’t have any idea about Malayalam (or any other Indic language [I can deal with Latin and Greek scripts only, I’m afraid]), but this seems to work fine. \mainlanguage[ml] \definefontfamily [malayalam] [rm] [RIT Rachana] [features=malayalam-two] \setupbodyfont [malayalam] \starttext \tf അദ്ധ്യായം\\ \em അദ്ധ്യായം\\ \bf അദ്ധ്യായം\\ \em അദ്ധ്യായം \stoptext Fonts are RIT Rachana from http://www.rachana.org.in/. The relevant feature here malayalam-two. I used serif (or rm), since the font looked to me more serif than sans-serif (Latin glyphs are clearly from a serif font).
The expected form is show in libre office with the same text and font, attached as an image
I would say that with malayalam-two ligatures are the same ones as in LibreOffice. Just in case it might help, Pablo -- http://www.ousia.tk

Hi Ajith, it isn’t clear to me whether you got the right ligatures with the sample included in https://mailman.ntg.nl/pipermail/ntg-context/2021/102635.html. I also wonder whether the feature "malayalam-two" got you the proper ligatures for your original sample included in https://mailman.ntg.nl/pipermail/ntg-context/2021/102631.html.

Hi Pablo,
I am not sure if my previous mail was delivered or not.
I didn't get the correct ligatures even after copy pasting the code you
provided (incluing the feature "malayalam-two").

In such cases, it is always useful to include the output of `context --version` to help debug why the output is different. Aditya

This is more than 3 years old! You will need to update. Not sure if there is a debian package for LMTX. You can always install it in parallel to the system installation by following the instructions on the wiki. Aditya

Hi Ajith, as Aditya mentioned, this version is too old (maybe it even lacks the mlm2 script). This old version won’t be fixed now (I’m afraid). I hope it helps, Pablo -- http://www.ousia.tk

Hi Pablo and Aditya,
Thanks to your help, I installed the latest version from context garden
and the ligatures are shown properly.
I was under the impression that updating through Debian was enough.
Thanks a lot,
ajith

Hi Pablo,
Just to be sure that you have the correct ligature, will you please
share a picture or pdf of the rendered text?
