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

[Kevin Ushey]

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
