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

[Vinh Nguyen]

Hi everyone,

Was curious if anyone was able to print spark histograms from the
skimr in the text console of Emacs ESS?  Tried setting to Chinese
locale, playing around with environment variables, but can't get
things to print as described here:
https://github.com/ropenscilabs/skimr/issues/246

I'm able to print on the regular R console by setting to the Chinese
locale and using the NSimSun font as described here
(https://stackoverflow.com/questions/44253848/skimr-cant-seem-to-produce-the-histograms),
but no luck on the Emacs ESS side.

Curious if others have gotten this to work.  Thanks!
