Canonical Combining Class - CCC23

CCC23 is a specific value within the Canonical Combining Class system that marks a character as having a fixed, non-reordering class of 23, which is used for certain diacritical marks that attach above or below a base character. This class number indicates that such marks do not interact with other combining marks in a way that requires reordering during normalization, meaning they maintain a consistent position relative to the base. Characters assigned CCC23 are typically positioned with a specific vertical attachment, and their class value ensures predictable stacking behavior when multiple marks combine, without priority shifts. This helps maintain stable text rendering and canonical equivalence for sequences containing these marks.
