[ESS] Print spark histograms from skimr package in Emacs ESS on Windows

[Vitalie Spinu]

Ok, I see. This is linux but I recall (from many years ago when I worked on
Windows) being able to fix such issues by explicitly specifying the codding
system of the process.

I still have this line commented out in my init file:

 (set-buffer-process-coding-system 'windows-1252 'windows-1252)

Try 'utf-8 or variants displayed by M-x list-coding-systems. If this works, you
can either set in ess-R-post-run-hook or in process-coding-system-alist.

I cannot investigate this further on Windows at the moment, sorry.
