U+02CB "ˋ" Modifier Letter Grave Accent Unicode Character

U+02CB "ˋ" Modifier Letter Grave Accent is a diacritical mark in the Unicode standard, classified as a modifier letter rather than a combining character, meaning it is intended to be used as a standalone symbol that modifies the phonetic value of a preceding letter. It typically represents a falling tone or a low tone in linguistic transcription systems, such as the International Phonetic Alphabet or various romanization schemes for tonal languages like Chinese or Vietnamese. This character is distinct from the similar-looking combining grave accent (U+0300), as it is a spacing glyph that occupies its own horizontal space and is not automatically attached to a base character.
