R help - Sep 2022 - How to set default encoding for sourced files

?options

options(encoding = "utf-8")
in a startup file or function should presumably do it. See ?Startup

Thanks everyone. Setting encoding in options in Rprofile.site has taken 
care of it.

Curiously, it doesn't seem to solve the whole problem for Rscript 
though. I checked that Rscript is indeed picking up the default encoding 
from options, but it's complaining about seeing an unexpected input in
dat$l?nea <- ....
immediately following the l when I run
Rscript myfile.R.
So, it would appear that Rscript is not using source to read in the R 
script. Mind you, if I do
Rscript -e source('myfile.R')
it works properly just like in Rgui.

Once again, Thanks heaps.

Cheers,
Andrew.
