R devel - Jun 2020 - Possible Bug: file.exists() Function. Due to UTF-8 Encoding differences on Windows between R 4.0.1 and R 3.6.3?

Dear R Developers,

I am having an issue with the renv package and R 4.0.1, which I
suspect is related to base R and not the renv package itself, as with
R 3.6.3 such an "error" does not appear.

The error is raised by a file.exists() path, and path
"C:\Users\J-tel\Documents", which in R 3.6.3 is read correctly, but in
R 4.0.1 fails (Probably because of the "-" symbol), and I suspect it
might be related with the new UTF-8 usage on Windows 10?
(https://developer.r-project.org/Blog/public/2020/05/02/utf-8-support-on-windows/index.html)

I have also checked file.exists() function and its internals, and seem
not to have happened changes in the meanwhile within them:

Dear Juan,

I don't see what is the problem from your report. Please try to create a 
minimal but complete reproducible example that does not use the renv 
package. Perhaps you could use the R debugger (e.g. via 
options(error=recover)) to find out what is the argument that 
file.exists() has been called with. And then you could try just to call 
file.exists() directly with that argument to trigger the problem.

It may be that the argument has been corrupted/is invalid in the current 
native encoding. If that is the case, the next step would be to find out 
who corrupted it (renv, R, something else). The error is displayed when 
a path name cannot be converted from the current native encoding to 
UTF16-LE.

The experimental support for UTF-8 as native encoding on Windows 10 is 
only available in a custom build of R, like the one I linked from my 
blog post.

Thanks
Tomas

So a bug in `renv` as it does not account for changes in R 4.0.0 ?

Stuff happens. I just fixed an 'change in R 4.0.0' for one small aspect
of
Rcpp(Armadillo) (namely the change in package.skeleton() and NAMESPACE).

Hi Juan,

For bug reports to R, you should attempt to create a
minimally-reproducible example, using only R's builtin facilities and
not any other addon packages. Given your report, it's not clear
whether the issue lies within renv or truly is caused by a change in R
4.0.0.

Also note that you have not supplied a minimally reproducible example.
If at all possible, you should be able to supply some code that
reproduces the issue -- ideally, one should be able to just copy +
paste the code into an R session to see the issue arise. Presumably,
if the issue is indeed in base R, then you should be able to supply a
reproducible example of the form:

    path <- "path/that/causes/issue"
    file.exists(path)

Alternatively, if you can distill this into a minimally-reproducible
example that does require renv, then you should report that to the
maintainer of renv (me), not this mailing list.

Best,
Kevin

Hi Tomas,

I received a report about R 4.0.0 in the knitr package
(https://github.com/yihui/knitr/issues/1840), and I think it is
related to the issue here. I created a minimal reproducible example
below:

owd = setwd(tempdir())
z = 'K\u00e4sch.txt'
file.create(z)
list.files()
file.exists(list.files())
setwd(owd)

Output:
> owd = setwd(tempdir())
> z = 'K\u00e4sch.txt'
> file.create(z)
[1] TRUE
> list.files()
[1] "K?sch.txt"
> file.exists(list.files())
[1] FALSE
> setwd(owd)
I wonder if it is expected that file.exists() returns FALSE here.
> sessionInfo()
R version 4.0.1 (2020-06-06)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 7 x64 (build 7601) Service Pack 1

locale:
[1] LC_COLLATE=English_United States.1252  LC_CTYPE=English_United States.1252
[3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C
[5] LC_TIME=English_United States.1252
system code page: 936

FWIW, I also tested Chinese characters in the variable `z` above, and
file.exists() returns TRUE only after I Sys.setlocale(, "Chinese").

Regards,
Yihui
