Hi Golferwu
This sound like exact same problem I have seen - just on a Danish Windows 10 installation.
I was able to solve by changing region setting in windows controlpanel for "program that don't use Unicode"
I changed, in my case Danish, to Latin (world) and unchecked "Beta: Use Unicode UTF-8..."
Like this in a Danish installation. Don't not the precise wording in an English instalation (or Chinese installation
)
Requires most likely restart and admin rights
My guess is it will also solve in your case - I hope so
Sessioninfo now is without codepage 65001 - on my PC like this:
locale:
[1] LC_COLLATE=Danish_Denmark.1252 LC_CTYPE=Danish_Denmark.1252
[3] LC_MONETARY=Danish_Denmark.1252 LC_NUMERIC=C
[5] LC_TIME=Danish_Denmark.1252
