From what I gathered:

It is not possible to "install" this font on windows
Font in question is supported by freetype
There is already TODO in the code, to implement fix (find nearest supported font size and use that if our requested size is not found)
I have been able to use different type of font, like github.com/eosrei/emojione-color-font

Even if use of this font was fixed, the output would be monochromatic without shading.
I don't know what it would take to support color fonts, but I guess it won't be particularly easy.

I wont be able to work on this anytime soon, but I will keep this in tracker, if any dev will be interested to solve this.
