Underscore does not appear in script

[harD2]

I am running Ubuntu 22.04, though this has been an ongoing issue since I was running 20.04. The underscore in my scripts does not always show up. It appears as though there is a space there, but when the script it run, you can see the underscore in the terminal. It's mostly a pain for troubleshooting. I tried changing the appearance and font in global options, but it did not solve the problem. Unfortunately, since I can't figure out what prompts the glitch, I cannot provide a reproducible example. It does not seem to be an issue with a certain package, as far as I can tell. If I close and reopen the script, the underscores are still missing.

Here's some potentially relevant info:

The underscore in my scripts does not always show up. It appears as though there is a space there, but when the script it run, you can see the underscore in the terminal.

Do you mean in your source Rmd file ? Is it when opening in the RStudio IDE ? Another tool ?

Or Do you mean in the resulting document ? The HTML or PDF book ?

How does it relate to bookdown ? Is this happening only with such project ?

Without much information it is hard to see exactly the situation. An example would help. I am just not sure this is something related to bookdown for which this issue tracker is about. But maybe I am missing something...
