Canonical Combining Class - CCC107

CCC107 is a specific numeric value assigned to certain characters, indicating they are positioned directly above the base character in a combining sequence. This class is used for marks like some vowel signs or diacritics that attach to the top of the preceding letter, such as certain Arabic or Hebrew pointing marks. A character with CCC107 will reorder before characters with lower class values during normalization, ensuring that visual stacking order is preserved in the canonical decomposition. It effectively controls the sequence of glyph placement for correct text rendering, particularly in scripts where multiple marks combine vertically.
