This can be extremely hard to fix. https://discord.com/channels/1054443721975922748/1225462045583872083

In short, when layouting texts in math, typst has special code path for:

  1. single letter
  2. numbers And spaces are eaten sometimes.

The tricky part is that this happens in layout stage, where everything is flattened. It's impossible to tell which Text comes from content block and whch text comes from math.

Maybe we can switch to strings for simple \text and textmath for complex ones? cc @OrangeX4 Although I don't know if strings can fix this problem

OrangeX4 commented 3 months ago

I think this can work, which means we need to first check if there are any special characters like the dollar sign $ inside \text{}, and then choose to convert them as string or content.
