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

[Vitalie Spinu]

Hi Vinh,

It works for me out of the box, no need for Chinese locale or R specific tricks:

   
   Variable type: numeric 
        variable missing complete   n mean   sd  p0 p25 median p75 p100     hist
    Petal.Length       0      150 150 3.76 1.77 1   1.6   4.35 5.1  6.9 ▇▁▁▂▅▅▃▁
     Petal.Width       0      150 150 1.2  0.76 0.1 0.3   1.3  1.8  2.5 ▇▁▁▅▃▃▂▂
    Sepal.Length       0      150 150 5.84 0.83 4.3 5.1   5.8  6.4  7.9 ▂▇▅▇▆▅▂▂
     Sepal.Width       0      150 150 3.06 0.44 2   2.8   3    3.3  4.4 ▁▂▅▇▃▂▁▁

My bet is that it's your emacs font which doesn't recognize those Unicode
characters.

In my experience DejaVu is among the most complete fonts so I do this in my .emacs:

  (set-face-font 'default  "DejaVu Sans Mono-9.5")

You can see all fonts on your machine with by calling (font-family-list).

HTH,

  Vitalie
