How to combine italic text with superscript in mixed content?

Questions
1

I’m trying to format Vibrio^(ΔACD) where “Vibrio” is italic and “ΔACD” is superscript, but can’t get it to work.

Attempted:

_Vibrio_$^(Delta"ACD")$

Error: “Unexpected hat”

Also tried:

  1. $italic("Vibrio")^(Delta"ACD")$ - Works, but “Vibrio” renders in math font instead of text italic
  2. _Vibrio_#super[$Delta$ACD] - Only Δ is superscripted, not “ACD”

What’s the minimal way to achieve italic text followed by superscript that includes both a Greek letter and regular text?

I think there are few solutions, but quotes seems like an easy one:

_Vibrio_$""^(Delta"ACD")$

Though I think there probably should be a canonical way. I guess it might’ve been

_Vibrio_#super[$Delta"ACD"$]

but it doesn’t work.

Thank you this works and is simple enough. Can you explain why this works but without the double quotes (before Delta) it doesn’t. Is this an expected behavior?

^ is the shorthand for math.attach, you must provide the base content. Empty quotes just happen to output nothing. See https://typst.app/docs/reference/math/attach/#syntax.

If you don’t actually need math mode, just the greek letter, you can also use the letter plainly:

_Vibrio_#super[#sym.Delta;ACD]

The semicolon here is to terminate the Delta identifier without inserting whitespace. The superscript will not use the math font.

I assume you meant the reverse—Δ is not superscipted in my testing. I have reported this on Github: Math within `super` or `sub` is not shown as super/subscript · Issue #7673 · typst/typst · GitHub

Yes, you are right. Delta is not superscripted in mine too.

Thank you, this is good to learn. For now, I am using _Vibrio_$""^(Delta"ACD")$ as I prefer the clarity of the math mode text in superscript.
