Thanks.

For those who can't be bothered to look (largest file 103 kB) - or have
stiff necks and can't read Tamil sideways (2 of the files). the schemes used
are:
Kannada - superscript, after ligature.
Telugu - superscript, after akshara. Shows a superscript 1.
Nagara - subscript, after ligature - note occurrences of bhu. No examples
of -i + number.
Sanskrit - subscript, after ligature - note ghau, with 4 before length mark,
in title of section 45.
I take it that by 'right after a consonant' you mean right after the glyph
containing the consonant, so that the number always follows vowel signs I,
II, U and UU.
The 2-dotted Tamil visarga shows up again. Who's going to propose TAMIL
SIGN TRUE VISARGA? Is there a problem showing that it is not a glyph
variant of aytham?

Of course, the problem only arises when the superscript/subscript comes
before vowel sign AA or AU length mark, including the cases where these are
parts of compound vowels. I think a quick fix would be to allow them to be
independent of an akshara, as though they were letters (category Lo) like
Thai sara AA rather than marks (category Mc). I suppose this would weaken
error checking by the renderer.
