U+1222D "𒈭" Cuneiform Sign Mu over Mu Unicode Character

U+1222D "𒈭" Cuneiform Sign Mu over Mu is a compound sign from the ancient cuneiform script, representing the syllabic value "mu" written as one standard "mu" sign stacked vertically above another. This ligature was used in Sumerian and Akkadian languages on clay tablets, often appearing in personal names, royal inscriptions, or lexical lists to indicate a reduplicated or emphatic form of the sound. Its inclusion in the Unicode Standard under the Sumero-Akkadian Cuneiform block helps preserve the complex orthography of Mesopotamian writing systems for digital texts and scholarly research.
