[R-pkg-devel] Windows R 4.2.0 package will not load with UTF-8 encoding

[Joseph Park]

Thank you for the check of the CRAN builds.  I also checked that as a first
step.  Perhaps there is some difference between the CRAN setups, as I have
reproduced this on 3 Windows 10 machines with clean installs of R 4.2.0,
and it has been reported by other users.  I also noted in the post that
building and installing via devtools reports success (  ** testing if
installed package can be loaded from temporary location ), however, a
subsequent attempt to load hangs.
