Canonical Combining Class - CCC33

CCC33 is a specific numeric classification assigned to certain diacritical marks, indicating they attach below the base character and are positioned above the preceding mark when stacked. This value, part of a scale from 0 to 255, denotes a particular level of reordering priority during text normalization, ensuring that combining characters are processed in a consistent sequence. Marks with CCC33, such as some subscript or below-attached signs, are distinguished from those with lower or higher values, which affect whether they shift relative to other combining marks. In practice, CCC33 helps determine the visual order of stacked diacritics, ensuring correct rendering and canonical equivalence across different fonts and systems.
