This is not a duplicate, different color font technologies need totally
different handling. Each needs a separate tracking bug.

For screen rendering they should already supported on Linux if you have
FreeType 2.10.x and Cairo 1.16.x, and should be supported on recent enough
macOS systems (disdn’t test that, though). On Windows it would require calling
the relevant DirectWrite APIs
(https://docs.microsoft.com/en-us/windows/desktop/directwrite/color-fonts#using-color-fonts-with-directwrite-and-direct2d)

For PDF, we would need to call HarfBuzz to decompose the color glyph layers
before writing them to the PDF, should be a couple of days work or so if
someone is interested.

What's the status with this? How difficult would it be to support this now that

Althrough HarfBuzz added support in version 1.7.6, there is no APIs published
to use them. So we should waitimg for new release, or giving a hand to fix it
soon.
