title: degree symbol incorrect in ggplot map axis labels on Windows 10
body: <p>This question is very similar to <a href="https://stackoverflow.com/questions/57467046/degree-symbol-incorrect-in-map-axis-labels">r - degree symbol incorrect in map axis labels</a>, though that was on a Linux machine. I'm experiencing a similar issue on Windows 10.</p>
  <pre><code>library(sf)                                            
  library(ggplot2) 
                                        
  nc = st_read(system.file(&quot;shape/nc.shp&quot;, package=&quot;sf&quot;))
  
  ggplot() +                                             
    geom_sf(data = nc)
  </code></pre>
  <p>Produces the following:

  <p>I expect the degree symbols to render properly, and suspect this has something to do with Windoze fonts. However, I'm not sure how best to address the matter.</p>
  <p>The <a href="https://stackoverflow.com/questions/57467046/degree-symbol-incorrect-in-map-axis-labels">answer</a> to the other question involves editing a <code>/etc/fonts/local.conf</code> file. I find several of these files on the system, one of them is in the R directory but for an older version of R. I'm a bit weary of editing random config files without understanding what I'm doing. Any insight would be much appreciated.</p>
