Bug description

Rstudio server crashes when auto-complete triggers on a data frame using non-ascii characters in variable names such as å, ä, ö. Here is an exampe of the error message appearing:

This was first detected in a github issue here using a dataframe containing column names written in japanese. In that thread there are more examples.

It has since been fixed in RStudio Server 2024.04.1+748 and 2024.07.0-daily+102 on Ubuntu 22.

So a fix for this issue could be to simply update the rstudio version in the rocker image, that would be highly appreciated. Could a fix for this be implemented within the coming weeks? Cheers.

How to reproduce this bug?

Log in to a Rstudio server session, open up a new R-script and type the following:

library(tidyverse)

df <- tibble(ärendenummer = c("a"), omrade = 1)
df

df |> 
  # after the comma, trigger auto-complete with ctrl+space and the session will crash
  select(ärendenummer, )

@emilwest Workaround:

library(tidyverse)

df <- tibble(ärendenummer = c("a"), omrade = 1)
df

df |> select("ärendenummer", )

Do you think this is closed by #819?

Thanks for such a quick fix! Can confirm that the bug no longer appears in the latest updated image rocker/tidyverse:4.4.0 on rstudio server 2024.04.1+748.
