Canonical Combining Class - CCC122

CCC122 is a specific numeric value assigned to certain combining characters, indicating their canonical ordering behavior during text normalization. It represents a high priority class, meaning these marks are positioned very close to the base character they modify, typically before most other combining marks in the canonical decomposition sequence. Characters with CCC122, such as some vowel signs or diacritics used in scripts like Devanagari or Arabic, are placed immediately after the base character and before any other combining marks with lower class values. This ordering ensures that when text is decomposed or recomposed, the visual or logical sequence of marks is preserved correctly without reordering errors. Practically, CCC122 matters for sorting, searching, and rendering complex scripts, as it dictates how accents or vowel points attach to their base letter in a predictable, standardized way, even when characters are stored in different orders in memory.
