[google-maps] Google maps Marker Label with multiple characters

As of API version 3.26.10, you can set the marker label with more than one characters. The restriction is lifted.

Try it, it works!

Moreover, using a MarkerLabel object instead of just a string, you can set a number of properties for the appearance, and if using a custom Icon you can set the labelOrigin property to reposition the label.
