Emoji Modifier Base - Yes
Yes is the Unicode character property value that identifies characters capable of being modified by an emoji modifier, such as skin tone variations. These base characters, which include human figures, body parts, and certain gestures, are designed to combine with modifiers like the Fitzpatrick scale tones (e.g., light, medium-dark) to represent diverse appearances. For example, a waving hand sign or a person running can be followed by U+1F3FB through U+1F3FF to change their displayed skin color. This value ensures that only appropriate characters accept such modifications, preventing nonsensical combinations with objects or symbols. It underpins inclusive visual communication across platforms by enabling consistent, user-selected representation of people in digital text.
