When the US Supreme Court legalized same-sex marriage in June 2015, a rallying cry went up for a rainbow flag emoji to celebrate the occasion. Noah Slater, who identifies as a “queer trans feminist nerd,” emailed the Unicode consortium-the organization responsible for approving emoji-to say that “there is a clear need for a rainbow flag that unambiguously symbolizes queer pride.”
