Canonical Combining Class - CCC11
CCC11 is a specific numeric value assigned to certain characters, indicating that they are positioned above their base character when combining marks are applied during text rendering. This value is part of a scale from 0 to 240, where higher numbers generally correspond to greater spatial separation from the base, and CCC11 specifically denotes a fixed position above the base, not relative to other marks. It is used for characters like some vowel signs or diacritics that sit atop the letter, ensuring consistent ordering when multiple combining marks are present. This ordering helps software correctly stack or sequence marks to avoid visual ambiguity. CCC11 does not imply a particular script or language, but rather a geometric placement rule that must be followed for proper text display across different systems and fonts.
