EMACS encoding issues Windows 11

Question

I am having encoding issues with EMACS (ESS). Part of the problem is that many of my file paths contain a special character (ý). These characters keep getting converted to "ý" when I close and reopen the buffer.

C-h v buffer-file-coding-system RET used to give:

Its value is ‘iso-latin-1-unix’
Local in buffer file.r; global value is iso-latin-1-dos

I added (setq-default buffer-file-coding-system 'utf-8-unix) to my init.el file, and now C-h v buffer-file-coding-system RET gives:

Its value is ‘iso-latin-1-unix’
Local in buffer file.r; global value is utf-8-unix

If I correct the letters and use C-x RET r utf-8-unix RET they get re-written as \375.

I added the following lines to my init.el (setq-default buffer-file-coding-system 'utf-8-unix) (setq-default coding-system-for-read 'utf-8-unix) (prefer-coding-system 'utf-8-unix) And now C-h v buffer-file-coding-system RET gives:

Its value is ‘utf-8-unix’
Local in buffer file.r; global value is the same.

but R in EMACS ESS no longer works. Shift-enter to start the minor process and execute a line of R code causes EMACS to freeze and all I get is a spinning wheel until I force quit.

So I removed those lines from my init.el to restore R. When I start R there is a error message "Error: invalid multibyte character in parser at line 1" which has to do with setwd() as the file path has the character ý in it.

If I put file.r into a directory that does not have ý in the path, everything works correctly.

I solved it by adding these three lines to my init file:

(setq-default buffer-file-coding-system 'utf-8) <br/> 
(setq-default coding-system-for-read 'utf-8) <br/> 
(prefer-coding-system 'utf-8)
