U+1DC8 "᷈" Combining Grave-Acute-Grave Unicode Character

U+1DC8 "᷈" Combining Grave-Acute-Grave is a diacritical mark used in historical and phonetic scripts, primarily within the International Phonetic Alphabet or medieval Latin notation, to indicate a specific tonal contour or pitch pattern that rises and then falls, combining a grave accent, an acute accent, and another grave accent in a single combining character. It is designed to be placed above a base letter, such as a vowel, to modify its pronunciation without altering the underlying orthography, and it is part of the Combining Diacritical Marks Supplement block. This character is rarely encountered in modern text but serves scholarly purposes in linguistics, musicology, or textual criticism where precise prosodic information must be encoded.
