I would recommend you use the Rtools for the respective version of R. If 
this is about R-devel or R-patched (to be 4.2), use Rtools42. If this is 
about R 4.1 or R 4.0, use Rtools40. You can have both installed in the 
system at the same time. These are tuned to work and have the needed 
tools so that you are least likely to run into problems. If you run into 
problems, still, it is easier to get help, and if you find something 
broken there, others would more likely benefit from the subsequent fixes.

The warning of "Setting LC_CTYPE=en_US.UTF-8 failed" is probably because 
LC_CTYPE or LC_ALL is set to that value in the shell, but R cannot set 
UTF-8 to be the current encoding for some reason (R version is too old, 
the Windows version is too old, etc). You would need to provide more 
details if you wanted to know exactly, why, but in principle - on such 
systems, simply clear LC_CTYPE and LC_ALL before running R.

The error about the missing DLL when running QPDF is probably because 
QPDF was not installed correctly, a runtime library is not on PATH or 
not available at all. You would not run into this problem with Rtools 
(either version), which include QPDF. But in principle, you can install 
QPDF from its official installation and put it on PATH to be used.
