U+A8E8 "꣨" Combining Devanagari Digit Eight Unicode Character

U+A8E8 "꣨" Combining Devanagari Digit Eight is part of the Devanagari Extended block and functions as a combining mark used in the Sanskrit transliteration system known as the Saurashtra script or in certain scholarly notations for Vedic texts. Unlike a standalone digit, this character attaches to a preceding base character to modify its representation, specifically indicating the numeric value eight within a combined diacritical context. It is employed in specialized linguistic and historical documentation to encode numerals that interact with adjacent characters, supporting precise transcription of ancient manuscripts where digits are written as combining forms rather than independent symbols.
