Using Esri Icon Fonts with map graphics

When the ArcGIS API for JavaScript stylesheet https://js.arcgis.com/4.4/esri/css/main.css is included in a web page, the Esri Icon Fonts are immediately available for use. One potential use of the Esri Icon Fonts is to use them as symbol property of Graphic. In the code snippet below a TextSymbol is created by specifying the color, text, and font. The font property is created by autocasting the Font Class.

var textSymbol = new TextSymbol({
  color: "#7A003C",
  text: "\ue61d", // esri-icon-map-pin
  font: { // autocast as esri/symbols/Font
    size: 20,
    family: "CalciteWebCoreIcons"
  }
});
