U+1DC6 "᷆" Combining Macron-Grave Unicode Character

U+1DC6 "᷆" Combining Macron-Grave is a diacritical mark used in phonetic and linguistic notation, designed to be placed over a base letter to modify its sound value by combining a macron, which typically indicates length, with a grave accent, often associated with low or falling tone. This character belongs to the Combining Diacritical Marks Supplement block and is intended for applications such as the International Phonetic Alphabet or scholarly transcriptions where precise tonal or prosodic information must be conveyed alongside a vowel or consonant. It is visually rendered as a small, double-hooked symbol that merges a horizontal bar with a downward leftward slope, and it must be applied to a preceding base character to function correctly in digital text.
