This is a follow-up to this question.
The accepted answer tells me that OpenType math fonts typically include (in the same font file) optically scaled glyphs for script and script script sizes. I have looked for these glyphs in the Cambria font and in Latin Modern Math, and I can't find them. I have tried using the Windows Character Map app, and also tried opening the fonts in FontForge. No luck.
Can someone tell me the code points (hex indices) of these subscript characters, please, so that I can hunt them down.
Edit
I see that Unicode includes
U+2099: LATIN SUBSCRIPT SMALL LETTER N
U+207F: SUPERSCRIPT LATIN SMALL LETTER N
But I have read that these should not be used for mathematics.

Unicode is not the only way to access a glyph. Glyphs also have names and an index number ("slot"). In the case of the script and script script the glyph names are build by adding
st
andsst
and you can use these names to find the slots and the glyphs: (I'm setting the math font as main font to avoid to have to struggle with the mathcodes).
