Session details:

R 4.4.3 and R 4.5.1

Describe the issue:

Positron is inserting Escape and Bell characters into R markdown with {roxygen2} while running devtools::document(). The same characters are not added when running in RStudio

Positron creates this line:

#> i Run ]8;;x-r-run:admiral::get_duplicates_dataset()admiral::get_duplicates_dataset()]8;; to access the duplicate records}\if{html}{\out{</div>}}

RStudio creates this line:

#> i Run `admiral::get_duplicates_dataset()` to access the duplicate records}\if{html}{\out{</div>}}

Steps to reproduce the issue:

1. Run devtools::document() on the following file from {admiral}:
   https://github.com/pharmaverse/admiral/blob/main/R/derive_extreme_records.R

Expected or desired behavior:

See RStudio output above

Were there any error messages in the UI, Output panel, or Developer Tools console?

No

Start with the R: Document R Package command and reproduce the issue by running devtools::document() on R/derive_extreme_records.R from the linked admiral package. Trace how the command launches R and compare its output with the RStudio example; done means the generated roxygen2 text contains backticks without Escape or Bell characters.
