A human nose. May be used to indicate smelling, or something that smells.
Nose was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
The Nose emoji supports skin tone modifiers. A yellow (or other non-human) skin tone should be shown by default, unless an emoji modifier is applied.
Platforms without support for emoji modifiers display a missing symbol character (box with a cross, alien, or question mark in it) next to any modified emoji.
