thanks a lot for the very nice code :) :) :)
The second example (H_2^+) does not return expected result - it
should have been

If your question is of interest to others as well, please add an entry
(text)
text = string.gsub(text,_,\\low)
text = string.gsub(text,%^,\\high)
tex.sprint(text)
end
\stopluacode
\def\molecule#1{\ctxlua{thirddata.molecule('#1')}}
hmm
Isn't better to remember original \molecule ?
I mean, something like
\let\ORIGINALmolecule\molecule
\def\molecule#1
