What's the right way to typeset the word bijection (a mathematical term meaning an injective and surjective map or, equivalently, a map having a two-sided inverse) in English?
bijection(i and j are separate glyphs)
bĳection(ĳ is a single glyph)
The same question can be asked about
(I'm not asking about Dutch. I'm also not asking what the typesetting programs currently do in English: their authors are sometimes terribly off, and the programs sometimes exhibit unintended behavior. I'm asking what should be the case in English.)
