Bibliography handles "$" weirdly

[genericusername3]

Description

I'm using the bibliography function to display the following bibliography item:

amazon-outage-costs:
  type: article
  title: Amazon ‘missed out on $34m in sales during internet outage’
  author:
  - Chapman, Ben
  date: 2021-06-08
  url:
    value: "https://www.independent.co.uk/news/business/amazon-down-internet-outage-sales-b1861737.html"
    date: 2023-11
  parent:
    type: periodical
    title: Independent.co.uk
    publisher: Independent

The output looks like this:

The Unicode quotes are handled correctly, but the dollar sign seems to be interpreted as the beginning of math mode. Replacing with \$ or \\$ to escape the dollar sign results in the title being truncated:

What does work, however, is using math mode to display a dollar sign:

  title: `Amazon ‘missed out on $dollar$34m in sales during internet outage’

I think text in bibliographies should not be parsed for math instructions, because titles don't usually include math formatting.

Typst version

From a quick check of arXiv catchup for mathematical physics, about 20% of the 91 papers contain math formatting in their title...

This is indeed a feature, but the fact that escaping it is broken is a bug.

In that case, maybe Typst (or Hayagriva) should emit a warning if there's incomplete math, because I would expect plain dollar signs aren't that uncommon in titles either.

But, in fairness, the first thing I tried was escaping the dollar sign so I'd agree it's not that big an issue if escaping works
