Demonstrates how to load SVG's as Leaflet icons via the data URI method.
Following was helpful to figure this out:

Thanks for the code. For others reading this, I found the following works better (for me at least) than encodeURI:
var url = "data:image/svg+xml," + encodeURIComponent(svg);
This allow double-quotes in the SVG and no need to do the additional replace on hashes.
Thanks @DynamicArray. var url = "data:image/svg+xml," + encodeURIComponent(svg); is the only code that worked for me
@stefanolaru it worked to me. Thanks
