U+22AF Negated Double Vertical Bar Double Right Turnstile

U+22AF was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script.

The glyph is a canonical composition of the glyphs Double Vertical Bar Double Right Turnstile, Combining Long Solidus Overlay. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored. The word that U+22AF forms with similar adjacent characters prevents a line break inside it.
