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

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: https://github.com/wch/r-source/blob/0e3b3182f87a60af4b0293a5410dde680b910f49/src/library/base/R/files.R https://github.com/search?q=SEXP%20attribute_hidden%20do_fileexists+repo:wch/r-source&type=Code Error Details:
