When to use it

⊯ writes U+22AF (Negated Double Vertical Bar Double Right Turnstile), a maths symbol from the Unicode Mathematical Operators block, encoded since Unicode 1.1. For more than a symbol or two, MathML, supported in all major browsers since 2023, gives proper maths spacing and layout.

The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
