Canonical Combining Class - CCC22

CCC22 is a specific value assigned to certain characters, indicating they belong to the “Above Right” positional class in the canonical ordering algorithm. This value dictates that when a character with CCC22 is combined with a base character, it is placed above and to the right of that base, typically in a diacritical or mark position. The numeric weight of 22 ensures that such marks are applied after characters with lower combining class values but before those with higher ones, maintaining a consistent visual and logical sequence for text rendering and normalization. CCC22 is used for a small set of marks, such as some Vietnamese or other Southeast Asian tone marks, that require this specific placement to display correctly.
