title: How to use browser's fonts with mapbox?
body: <p>I'm builing a POC with last Mapbox's version.</p>
  
  <p>From the same source I have two layers, one to show points, and the other one to print an hello world for each points :</p>
  
  <pre><code>layerPoint : {
      id : this.layerPointId,
      type : "circle",
      source : this.sourceId,
      paint : {
          "circle-color" : this.color,
          "circle-radius" : 4
      }
  }
  layerText : {
      id : this.layerTextId,
      type : "symbol",
      source : this.sourceId,
      layout : {
          "text-field" : "Hello world",
          "text-size": 12
      }
  }
  </code></pre>
  
  <p>I got an error on my console:</p>
  
  <pre><code>layers.l.text.uuid12987456.layout.text-field: use of "text-field" requires a style "glyphs" property
  </code></pre>
  
  <p>So I look <a href="https://www.mapbox.com/mapbox-gl-js/style-spec/#glyphs" rel="nofollow noreferrer">into Mapbox's doc</a> to see that I should add a glyph property if I need text-fiel. But what glyph property should I use if I want to got defaults browser or OS fonts? I don't need any icons and my POC must run on a disconnected environment.</p>
