That covers it all.

Thanks. I will request fedora and debian emacs maintainers to include this.

yes, indeed that is the case, see attached screenhsots. It worked in
Fedora by default and after unalias in debian.

yes. Parag has requested a dependency be added to emacs package.

yes, FreeMono does not have Malayalam glyphs, It would be a fallback
font. (Dejavu Sans Mono/FreeMono fallback to Lohit)

It is not working for me. I tried it as is and substituting
unicode-bmp with Rachana. Both cases it went to Lohit. Is it taking
this preference from fontconfig?

    xft:-unknown-Lohit
Malayalam-normal-normal-normal-*-20-*-*-*-*-0-iso10646-1 (#x3A)

Thanks for all the help.
