U+1AD1 "᫑" Combining Grave-Vertical-Line Unicode Character

U+1AD1 "᫑" Combining Grave-Vertical-Line is a combining diacritical mark used in the Bengali-Assamese script, specifically as part of the extended Vedic tone marks. It appears as a small vertical line placed above a base character to indicate a high-pitched tone or stress in the recitation of Vedic texts. This mark is distinct from other similar combining characters because it combines the function of a grave accent indicator with a vertical delineation, serving an essential role in preserving the phonetic and tonal accuracy of ancient Sanskrit hymns and liturgical chants.
