R: Unicode decode error('utf-8')

[HenliDreck]

Hi, I am trying to use REPL to replace Rstudio, while I encountered this:

When I use python in REPL though, there is no such problem. Given my dir of R and python are both in English, I have no idea why R does not work well.
I know there are already similar issues, but the problem does not go away only by changing subprocess_repl.py
