Part of making emojis more consistent is in the naming conventions. Unicode now tends to opt for more descriptive names for emojis to avoid divergent interpretations by designers across platforms. In her newsletter about the Emoji 14.0 release, chair of the Unicode Emoji Subcommittee Jennifer Daniel, explains: "If the existing 'pregnant woman' had been named 'woman with swollen belly' these new emoji would’ve followed suit." Had 🤰 Pregnant Woman been approved in 2021 under a more descriptive name, we might've been talking about the addition of “Man with Swollen Belly” and “Person with Swollen Belly” today instead of Pregnant Man and Pregnant Person. This is all part of the messiness of standardizing a standard.
