Eli> It should, and I thought HarfBuzz on Cairo already supported that?
It does, but with 'Noto Color Emoji' it doesnʼt work for all
codepoints.
Eli> Can you try this with hb-view and see if HarfBuzz produces a single
Eli> glyph/grapheme from this sequence?
For reference, since the documentation of hb-view is sadly lacking:
hb-view --output-file=foo.svg --font-size=14 \
/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf -u 1f469
produces a glyph with no skin tone. And
hb-view --output-file=foo.svg --font-size=14 \
/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf -u 1f469,1f3fd
Produces one with a medium tone. The skin tones are working for other
code points, so I donʼt know what's causing this particular problem.
