Pretty neat, but I changed a couple of small things so it works better with UTF-8 encoding :) https://gist.github.com/JacobDB/0ffffaf8e772c12acf7102edb8a302be

I tried encoding this svg: <svg width='20' height='20' xmlns='http://www.w3.org/2000/svg'><g transform='translate%28-13 -12%29' fill='none' fill-rule='evenodd'><path d='M0 0h45v45H0z'/><circle fill='%239B9B9B' cx='23' cy='22' r='10'/><path fill='%23FFF' fill-rule='nonzero' d='M27.3967 17l1.4296 1.5388-7.852 8.4516L17 22.7126l1.4296-1.5388 2.5447 2.739z'/></g></svg> and it took 3 seconds only for this scss code:

.foo {
  background-image: 
  url("data:image/svg+xml,#{url-encode("<svg width='20' height='20' xmlns='http://www.w3.org/2000/svg'><g transform='translate%28-13 -12%29' fill='none' fill-rule='evenodd'><path d='M0 0h45v45H0z'/><circle fill='%239B9B9B' cx='23' cy='22' r='10'/><path fill='%23FFF' fill-rule='nonzero' d='M27.3967 17l1.4296 1.5388-7.852 8.4516L17 22.7126l1.4296-1.5388 2.5447 2.739z'/></g></svg>")}");
}
