This character is a Other Letter and is mainly used in the Cuneiform script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+12034 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
ARAD, (also ΓR or NITΓ) is the capital letter-(majuscule) Sumerogram for the Akkadian language word "ardu", for servant. It is used especially in the introduction to the Pharaoh: for example "To King, Lord-mine (of Gods(pl)-mine, Sun-god-mine), message thus Xxxxxx, "Servant-yours"-(271). It is also used extensively in Amarna letter texts, the author, usually the "man of a city", (or scribe), where there is a constant reminder that he is a "servant", or "servant-yours"-(of the Pharaoh). Many letters are giving city-state status reports, but many are also requesting help with the Egyptian army troops-(Archers (Egyptian pitati), supplied by the Pharaoh).
