[R] How to set default encoding for sourced files

[Andrew Hart]

Thanks. The --encoding option indeed makes it all work. Rscript --help 
does not show the --encoding option in the list of options.

And yes, you are right. I was using R 4.1.2 when I first wrote to the 
list. I was experiencing a technical  issue with R 4.2.1 which was 
preventing me from switching over to it but I have a satisfactory 
solution to the problem now and have just moved to R 4.2.1. It seems 
that, on Windows at least, R 4.2.1 does indeed use utf-8 as its native 
encoding. I didn't realise this. At any rate, it looks like merely 
upgrading solves my encoding concerns without the need to set options or 
specify the encoding with Rscript. Very nice and kudos to the R 
developers for taking the leap!

Thanks everyone for your help.

Cheers,
Andrew.
