Thanks, I can reproduce the problem. Rgui uses via GraphApp an ANSI 
RichEdit window to implement the script editor. What happens is that the 
text obtained from that window is in Latin 1 encoding (on my machine, 
probably also on yours), even though Rgui runs in UTF-8 via the active 
code page specified in the manifest file, which I find rather 
surprising. You can see that even in R 4.1, you cannot use characters 
not representable in your native/ANSI encoding in the editor window. 
But, now you cannot even use characters with different representation 
between your ANSI code page and UTF-8 encoding (so only ASCII is safe). 
I will investigate further how this could be fixed, it may not be 
completely trivial as there are also other operations on the content of 
the window, and it would really be nice if the RichEdit window could be 
made to respect the active code page.

Best
