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

[Juan Telleria Ruiz de Aguirre]

Thank you Kevin, just checked that the error is solved in the latest
development version of "renv", and now it works as expected with R
4.0.1:

Sorry for posting in r-devel, I was not sure if it was a R or "renv"
error due to different behaviour in different versions of R 4.0.1 and
R 3.6.3 for conversion from UTF16-LE to UTF-8 encoding.

Will provide a better reproducible example next time and traceback the
error with options(error=recover)) to make sure.

Thanks,
Juan
