Many people connected to the African diaspora have Afros. And like anyone else, they send emojis to their friends — a zombie, say, or a mermaid or a genie.

But which emoji can they use to represent themselves?

Right now, 2,823 emojis are recognized by the Unicode Consortium, the nonprofit that provides standards for text on the internet and oversees emojis. Fifty-nine additional emojis are on the way, including a deaf person, interracial couples, a mechanical arm and falafel.

Yet there are still no emojis of any person with an Afro, even though symbols exist for women and men with long and short hair, curly and straight hair, and blond, black and red hair.

Rhianna Jones, 28, is on a mission to change that.

She and a friend, Kerrilyn Gibson, 25, have started a Change.org petition calling for the addition of an Afro emoji designed by Ms. Gibson. It has more than 2,000 signatures, and Ms. Jones said they planned to submit the emoji to the Unicode Consortium on Sunday.
