U+A823 "ꠣ" Syloti Nagri Vowel Sign A Unicode Character

U+A823 "ꠣ" Syloti Nagri Vowel Sign A is a combining diacritical mark used in the Syloti Nagri script, historically employed for writing the Sylheti language of northeastern Bangladesh and parts of Assam, India. This vowel sign attaches to a consonant letter to indicate the long vowel sound "a," as in the English word "father," and is distinct from the inherent vowel of the script, which is implied when no sign is present. It appears as a horizontal stroke placed above or to the right of the base consonant, modifying its pronunciation within the syllabic writing system.
