Composition Exclusion - No

No is the designation for characters that are not excluded from canonical composition, meaning they are allowed to participate in the process where a base character and a combining mark combine into a single precomposed character. This value indicates that a character does not have a specific exclusion listed, so it remains eligible for canonical decomposition and subsequent recomposition under Unicode’s normalization algorithms. In practical terms, this means such characters can be normalized to a composed form, which helps ensure text is stored consistently, though their inclusion depends on other rules governing composition, such as the character’s decomposition mapping and its compatibility status.

This is the default value, shared by most characters (310,260 in total), so no character list is shown.
