U+07EF "߯" NKo Combining Long High Tone Unicode Character

U+07EF "߯" NKo Combining Long High Tone is a combining diacritical mark used in the NKo script, which was created in 1949 for writing the Manding languages of West Africa, such as Maninka. This specific character modifies a base consonant or vowel to indicate a long, high tonal quality, an essential feature for distinguishing meaning in tonal languages. It appears as a small, slanted line placed above the letter it accompanies, and its inclusion in Unicode ensures proper digital representation and preservation of the NKo writing system.
