Google maps Marker Label with multiple characters

Question

I am trying to add a 4 character label (eg \'A123\') to a Google Maps marker which has a wide icon defined with a custom path.

OK, here is one solution I have come up with which is pretty messed up.

I put the full label text into the div using the fontFamily label attribute. Then I use querySelectorAll to match the resulting style attributes to pull out the refs and rewrite the tags once the map has loaded:

var label = "A123";
var marker = new google.maps.Marker({
  position: latLon,
  label: {
    text: label,
    // Add in the custom label here
    fontFamily: 'Roboto, Arial, sans-serif, custom-label-' + label
  },
  map: map,
  icon: {
    path: 'custom icon path',
    fillColor: '#000000',
    labelOrigin: new google.maps.Point(26.5, 20),
    anchor: new google.maps.Point(26.5, 43), 
    scale: 1
  }
});

google.maps.event.addListener(map, 'idle', function() {
  var labels = document.querySelectorAll("[style*='custom-label']")
  for (var i = 0; i < labels.length; i++) {
    // Retrieve the custom labels and rewrite the tag content
    var matches = labels[i].getAttribute('style').match(/custom-label-(A\d\d\d)/);
    labels[i].innerHTML = matches[1];
  }
});

This seems pretty brittle. Are there any approaches which are less awful?
