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+1230D forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
The Winkelhaken (German:[ΛvΙͺΕkΙlΛhaΛkΙn], "angular hook"), also simply called a hook, is one of five basic wedge elements appearing in the composition of signs in Akkadian cuneiform. It was realized by pressing the point of the stylus into the clay.
A single Winkelhaken corresponds to the sign U (Borger 1981 nr. 411, Borger 2003 nr. 661), encoded in Unicode at code point U+1230B π.
