Is it possible to use a font to provide the marker picture

[nickkellet]

I was looking at this example for Fontawesome Markers.

http://fontawesome.io/icon/map-marker/
https://github.com/nathan-muir/fontawesome-markers

new google.maps.Marker({
map: map,
icon: {
path: fontawesome.markers.EXCLAMATION_CIRCLE,
scale: 0.5,
strokeWeight: 0.2,
strokeColor: 'black',
strokeOpacity: 1,
fillColor: '#f8ae5f',
fillOpacity: 0.7,
},
clickable: false,
position: new google.maps.LatLng(lat, lng)
});

I could not see how to do this as all the examples provide a icon as URL.

eg
markers = handler.addMarkers([
{
lat: 0,
lng: 0,
picture: {
url: "https://addons.cdn.mozilla.net/img/uploads/addon_icons/13/13028-64.png",
width: 36,
height: 36
},
infowindow: "hello!"
}
I've been using http://chart.apis.google.com/chart , but I see it's now deprecated, I'd much rather use a font than making custom images for all the colors etc.

Thanks
