Canonical Combining Class - Attached Above Right

Attached Above Right is a value that indicates a diacritical mark should be positioned above and to the right of its base character, specifically with the mark’s right edge aligned near the base’s top right corner. This placement is used for certain spacing or combining marks, such as some vowel signs or modifiers in scripts like Devanagari or Thai, where the mark visually attaches to the upper right area rather than sitting directly above. It influences how text is rendered, ensuring the mark does not overlap the base incorrectly and maintains proper vertical stacking when combined with other marks. The value helps define precise ordering and positioning in complex text layout, particularly for shaping and reordering during rendering.
