The face of a girl, smiling. Differentiated from the woman emoji by the hairstyle which features pigtails which are not present on the woman.
Girl was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
The Girl 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.
