U+0340 "̀" Combining Grave Tone Mark Unicode Character
Unicode Version 17.0
̀
U+0340 "̀" Combining Grave Tone Mark is a diacritical mark used in the International Phonetic Alphabet to indicate a falling contour tone on a vowel or syllabic consonant. It modifies the preceding character by attaching to it as a combining mark, placing a grave accent above the base letter to denote a high-to-low tonal glide in linguistic transcription. This character has a canonical compatibility decomposition to the more common combining grave accent U+0300, and while rarely used in modern digital text, it remains a distinct formal entry in the Unicode standard for specialized phonetic notation.
