The Adisila font, developed Krishnaprasad and occasionally discussed on this list, does have the ligature in question. Hopefully the attached image comes through. The large number of "hacks" you've had to introduce to get Devanagari MT to do the right thing suggests to me that a different font might serve you better.

Dear Arlo,

looking into the Devanagari MT font table I am afraid to say that there is no /ḍbha/ conjunction preset, at least not in my version of the font (perhaps someone else might have a newer one). 

So as long as you are not modifying the original font adding a glyph, or you are setting up an XeLaTeX pseudo-‘glyph’, highly likely it won’t be possible. 

Working myself on a Devanagari font, I would recommend a simple font creator & editor (I use TypeTool 3) and / or a proper XeLaTeX build (in my font I am now up to ca. 2.800 akṣara commands). 

The problem, you’re confronted with, might be easiest solved with a basic font editor adding the conjunction glyph in question. Changing the font could also be a solution (e.g. Chandas/Uttara).

Best,


Raik Strunz

Dear colleagues,

Does anyone know a way to get the ligature ड्भि to display without virāma in Devanagari MT, if need be through some amount of XeTeXglyph fiddling?

I am pasting below the list of ligatures for which I have found it necessary so far to fake special measures using Devanagari MT. If it is clear that adopting a different font will make most of these special cases go away, please advise me.

Thank you, and best wishes,

Arlo Griffiths
