This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as independent.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+2ADD forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In model theory, a forking extension of a type is an extension of that type that is not free whereas a non-forking extension is an extension that is as free as possible. This can be used to extend the notions of linear or algebraic independence to stable theories. These concepts were introduced by S. Shelah.
