R 4.2.0: RStudio specific error with devtools::check() in accented path directory

[rempsyc]

Original GitHub issue: usethis cannot find path with accents. · Issue #1630 · r-lib/usethis · GitHub

---

In R 4.2.0, the following works in a path containing an accent:

usethis::create_package("D:/é/mypkg")
usethis::use_package_doc()
devtools::document(roclets = c('rd', 'collate', 'namespace'))

devtools::check() also works in the console, but NOT when using the Ctr+Shift+E shortcut, or using RStudio's Check button:

getwd()
"D:/é/mypkg"

devtools::check()
[...]

  Error in find.package(package, lib.loc) :

Seems like the accent "é" is being replaced with letter "C" in the path. I've tried restarting Rstudio and my computer, to no avail. Recommendation on GitHub issue was to come here. Can anyone replicate?

I can replicate on R4.2.0, RStudio 2022.02.2 + 485 "Prairie Trillium" Release (8acbd38b, 2022-04-19) , Windows 11.

I don't know if it's an {fs} bug though, as fs::path_wd() does return the correct path (i.e. with accent).

Thanks for reporting this! I will take a look and report back if we need to file an issue in RStudio -- this has been a known issue in R 4.2.x on Windows that we've already released some fixes for, but this may still be outstanding.
