U+12230 Cuneiform Sign Munsub

El Wikipedia tiene la siguiente información acerca de este punto de código:

Cuneiform is a logo-syllabic writing system that was used to write several languages of the Ancient Near East. The script was in active use from the early Bronze Age until the beginning of the Common Era. Cuneiform scripts are marked by and named for the characteristic wedge-shaped impressions (Latin: cuneus) which form their signs. Cuneiform is the earliest known writing system and was originally developed to write the Sumerian language of southern Mesopotamia (modern Iraq).

Over the course of its history, cuneiform was adapted to write a number of languages in addition to Sumerian. Akkadian texts are attested from the 24th century BC onward and make up the bulk of the cuneiform record. Akkadian cuneiform was itself adapted to write the Hittite language in the early second millennium BC. The other languages with significant cuneiform corpora are Eblaite, Elamite, Hurrian, Luwian, and Urartian. The Old Persian and Ugaritic alphabets feature cuneiform-style signs; however, they are unrelated to the cuneiform logo-syllabary proper. The latest known cuneiform tablet dates to 75 AD.

Cuneiform was rediscovered in modern times in the early 17th century with the publication of the trilingual Achaemenid royal inscriptions at Persepolis; these were first deciphered in the early 19th century. The modern study of cuneiform belongs to the ambiguously named field of Assyriology, as the earliest excavations of cuneiform libraries – in the mid-19th century – were in the area of ancient Assyria. An estimated half a million tablets are held in museums across the world, but comparatively few of these are published. The largest collections belong to the British Museum (approx. 130,000 tablets), the Vorderasiatisches Museum Berlin, the Louvre, the Istanbul Archaeology Museums, the National Museum of Iraq, the Yale Babylonian Collection (approx. 40,000 tablets), and Penn Museum.
