> The hieroglyphs don't have the emoji property
What does the emoji property mean, semantically? That the codepoint represents a pictograph or that vendors have “permission” to give it a colored, stylized representation? If we go with the first, then hieroglyphs should certainly be emoji. Although it seems unlikely (to put it lightly) that hieroglyph emoji would be deployed due to the burden on vendors, it does seem logically appropriate that we treat all pictographs equally, and aside from usage I see no difference between U+1F989 OWL 🦉 and U+13153 EGYPTIAN HIEROGLYPH G017 𓅓.
