I've contacted the processx package maintainer on a problem reported here
previously (see https://cygwin.com/pipermail/cygwin/2020-April/244667.html).
He suggested to try the github version but that triggered a different type of
error which does not seem to be package-specific.
1st try: build from a local copy of the github package sources with default
locale settings on a German Windows 10 system
install.packages("/cygdrive/c/Temp/processx-master",repos=NULL,type="source")

Warning message:

Noted. I will look on both the two issues but it could take a bit.
I never looked at the build process of R packages in such details
kind of "while you're at it": I've noticed one additional problem with non-ASCII
characters. This may or may not be related to the problem reported above.
Several packages throw an error during installation, in my case questionr,
readr, pls, and vegan. The output of the latter is shown here:
installing to /usr/lib/R/site-library/00LOCK-vegan/00new/vegan/libs
** R

** help

Error in Rd_info(db[[i]]) :
missing/empty \title field in
'/tmp/RtmprL23H1/R.INSTALLffe51949f2e2/vegan/man/sipoo.Rd'
Rd files must have a non-empty \title.
See chapter 'Writing R documentation' in manual 'Writing R Extensions'.
* removing ‘/usr/lib/R/site-library/vegan’
The file in question (man/sipoo.Rd) starts like this:
\encoding{UTF-8}
\name{sipoo}
\alias{sipoo}
\alias{sipoo.map}
\docType{data}
\title{ Birds in the Archipelago of Sipoo (Sibbo and Borgå)}
Please note that the encoding is set to UTF-8 explicitely. Nonetheless, the a
with overring in "Borgå" seems to mess up the title, which makes R think the
\title field is missing. Changing the å to a circumvents this problem. I've also
noticed that non-ASCII characters outside the title field do not hurt at all.
Add "Encoding: UTF-8" to the package DESCRIPTION file and remove from .Rd files,
as documented near the bottom of the section:
https://cran.r-project.org/doc/manuals/R-exts.html#The-DESCRIPTION-file
referenced by:
https://stackoverflow.com/questions/18080303/rd-files-with-different-encoding
the original issue was in a package that was following the rule, so
there is something at fault in the Cygwin R package reading UTF-8 files.
May be is the same root cause that is causing a single
fault in reading/writing during build test.
I am looking on the 4.0.0 before releasing but I am not a R user
so it takes time.

Marco
