Top And Right Value in Indic Positional Category Unicode Property

Top And Right is a value used to define how a dependent vowel sign attaches to a base consonant in Indic scripts, specifically indicating that the mark is placed both above and to the right of the consonant. This positioning occurs when the vowel sign’s shape extends vertically and also shifts horizontally, such as in certain forms of the Bengali and Oriya vowel signs for sounds like “o” or “au.” The value helps renderers correctly align the mark with the consonant’s visual footprint, avoiding overlap or misplacement, and is distinct from other positional categories like Top, Right, or Bottom. It ensures consistent typographic behavior across complex text shaping, where the sign’s contours require simultaneous elevation and rightward offset.
