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).

I would say that with malayalam-two ligatures are the same ones as in
LibreOffice.

Just in case it might help,

Pablo
