Full Composition Exclusion - No
No is the designation for characters that are not excluded from canonical composition, meaning they can participate in the standard normalization process where a base character and a combining mark are merged into a single precomposed form. This value applies to the vast majority of Unicode code points, including all basic Latin letters, common punctuation, and most scripts, allowing them to be composed normally when their decomposition mappings exist. In contrast to the "Yes" value, which marks characters as stable and never subject to recombination, "No" ensures that composable sequences, such as an "e" followed by an acute accent, can correctly transform into "é" during normalization forms like NFC. This behavior is essential for data interchange, as it enables text to be stored in a more compact and linguistically intuitive precomposed state without breaking equivalence.
