Emojis are created through a collaborative process that involves several organizations and individuals.
The Unicode Consortium, a non-profit organization that sets standards for software internationalization, approves and assigns unique code points to emojis. Emoji proposals are submitted to the Unicode Consortium by individuals, organizations, or companies, and are evaluated based on factors such as expected usage, distinctiveness, and compatibility with existing emojis.
Once a proposal is accepted and assigned a code point, it is up to individual vendors (such as Apple, Google, Microsoft, and others) to design and implement their own version of the emoji for their respective platforms or devices. Vendors may choose to interpret the emoji design in their own way, resulting in slight variations in appearance across different platforms.
Overall, the creation of emojis is a collaborative effort that involves input from various stakeholders, including Unicode Consortium members, designers, and software developers.
