Just a note about the Greek terminal form of sigma: when dealing with Greek numerals, ςʹ (the final form of sigma) is 6 while σʹ (the non-final form of sigma) is 200; they need to be differentiated whatever the font engine decides to render.

Thanks, good to know. I’ve also realised that determining which form to use in mathematical formulas is maybe not that straightforward.

Edit: by which I mean that I’ve only seen the non terminal form so far in maths but it’s hard to write an algorithm that distinguishes between a word ending in sigma and some juxtaposition of Greek variables.
