U+1E23 "ḣ" Latin Small Letter H with Dot Above Unicode Character

U+1E23 "ḣ" Latin Small Letter H with Dot Above is a specialized letter used primarily in the transliteration of certain African languages, such as Hausa and Ewe, where it represents a voiced glottal fricative or a distinct phoneme that differs from the plain letter h. It is also employed in some scholarly transcriptions of medieval texts or phonetic notations to indicate a specific breathy or murmured articulation. The dot above the h is a diacritical mark that modifies the base character, allowing it to denote a sound not covered by the standard Latin alphabet. This character is part of the Latin Extended Additional block in Unicode, which supports a wide range of orthographic needs for minority languages and linguistic research.
