Thanks to Suresh Kolichala and Dominik Wujastyk. Should I ever have difficulties handling the "ring below" characters I now know where to turn.
Coming back to my question:
I was looking for HTML (not HEX) definitions of r- and l- with ring below of the type
Ḁ (for CAPITAL LETTER "A" WITH RING BELOW).
This HTML definition is built on the DECIMAL code ("7680"), not the HEX code ("1E00") for that character. Allan Wood's lists give both where available (see here:
http://www.alanwood.net/unicode/latin_extended_additional.html).
As indicated, Gandhari Unicode has fixed definitions for the said r- and l- characters. This made me wonder whether they ever were "canonized", like so many other out-of-the-way characters that started as "private".
Apologies for not using the canonical language.
R.G.

Betreff: Re: [INDOLOGY] HTML definition of Unicode characters for r and l with "underring"?
But ring below is - as you observe correctly - not in the unicode standard as a single glyph. See, e.g.,
this list. The letter r + ring below is, as others have said, still fully achievable and fully Unicode, but it has to be rendered with a combination of the two glyphs r and the
non-spacing ring below.
Best,
Dominik
