This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as turnstile, proves, implies, yields and reducible.
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 mirrored into Left Tack. The word that U+22A2 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In mathematical logic and computer science the symbol ⊢ () has taken the name turnstile because of its resemblance to a typical turnstile if viewed from above. It is also referred to as tee and is often read as "yields", "proves", "satisfies" or "entails".
