Indic Positional Category - Bottom
Bottom is a categorisation for certain Indic script characters, typically vowel signs, that are placed below the consonant’s base form, often in a visually lower vertical position than other below-base marks. This value applies to dependent vowel signs that attach to the bottom of the consonant, such as the Telugu vowel sign U or the Kannada vowel sign U, indicating they occupy a specific slot in the script’s shaping logic. These characters are distinct from those set in the “bottom” position for stacking or reordering purposes, as “Bottom” specifically denotes a standard, non-stacked placement directly under the base character, used in shaping engines to correctly position the mark without altering its inherent form or interaction with adjacent consonants.
