It may be that I was trying to support an encoding of some of these vocalic forms. x

But the table could not work as it is, and I have deleted it. In what tests I have, this has not changed anything.

At the time I was working on this, it was my impression that the most common encoding for some of these forms was not explained by the Unicode Standard. Since then, the Standard has developed some discussion of the issue (see fig 12-4). But it was all miserably complicated, my last notes indicate that I was unsure of a couple of things at the time, and I can't get my head around the issue now.

I attach a test file with some tables from a thing I was writing at the time.
The final row in each table should show distinct forms.

That is true.

'blwf' decomp-vocalic-reph in Devanagari for Sanskrit
llvocalicdeva(ॡ) dev_ra.rphf
lvocalicdeva(ऌ) dev_ra.rphf

-- later --

'blws' local forms in Devanagari for Sanskrit-klrp
virama(्) llvocalicdeva(ॡ) dev_ra.rphf
virama(्) lvocalicdeva(ऌ) dev_ra.rphf

But what was this last table meant to accomplish?
It is quite possible that it was deliberate and working, and that later the 'blwf' table was added and broke it.

I have lots of notes on rare uses of vocalics, some saying that Unicode doesn't explain how to encode certain combinations. This may have changed -- those notes are 3-4 years old.
