Emoji Component

Emoji Component is a character classification that identifies the building blocks used to construct fully rendered emoji sequences. It covers elements like skin tone modifiers, hair components, and other parts that are not standalone emoji but combine with base characters, such as the ZWJ, variation selectors, or specific codepoints for eyes, mouths, or hands. This property helps systems recognize which characters are meant to be assembled into a composite emoji, rather than displayed individually, ensuring proper rendering across platforms. It is essential for parsing and displaying complex emoji like family groupings or person with profession, as it distinguishes these functional parts from ordinary text or complete emoji.
