Emoji Modifier Base - No

No is a designation indicating that a character does not serve as a base for emoji modifiers, meaning it cannot be followed by skin tone modifiers like those for Fitzpatrick scale variations. These characters are typically standard symbols, letters, punctuation, or other non-humanoid graphics that lack the specific structural role of supporting a modifier. As a result, they do not alter appearance when a modifier is appended, and such usage would be invalid or ignored in rendering. This classification applies to all characters that fall outside the defined set of modifier bases, ensuring consistent behavior across platforms when combining emoji sequences.

This is the default value, shared by most characters (310,205 in total), so no character list is shown.
