U+22D4 Pitchfork
U+22D4 was added in Unicode version 1.1 in 1993. It belongs to the block
This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as proper intersection.
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+22D4 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In differential topology, the transversality theorem, also known as the Thom transversality theorem after French mathematician René Thom, is a major result that describes the transverse intersection properties of a smooth family of smooth maps. It says that transversality is a generic property: any smooth map $f:X\to Y$, may be deformed by an arbitrary small amount into a map that is transverse to a given submanifold $Z\subseteq Y$. Together with the Pontryagin–Thom construction, it is the technical heart of cobordism theory, and the starting point for surgery theory. The finitedimensional version of the transversality theorem is also a very useful tool for establishing the genericity of a property which is dependent on a finite number of real parameters and which is expressible using a system of nonlinear equations. This can be extended to an infinitedimensional parametrization using the infinitedimensional version of the transversality theorem.
