U+1E21 "ḡ" Latin Small Letter G with Macron Unicode Character

U+1E21 "ḡ" Latin Small Letter G with Macron is a specialized letter used primarily in transliteration and linguistic notation, representing a voiced velar fricative or fricative-like sound, particularly in romanizations of Semitic languages like Arabic, where it corresponds to the letter ghayn. It consists of the standard lowercase "g" combined with a macron, a horizontal line placed above the letter to indicate a prolonged or emphatic pronunciation. This character is distinct from the plain "g" and is encoded separately in Unicode to support accurate textual representation in digital typography for scholarly and language documentation purposes.
