Does not force (⊮) is the Unicode character at U+22AE in the Mathematical Operators block. Official name: DOES NOT FORCE. In logic and forcing theory, M ⊮ φ means M does not force φ.

Prefer ⊮ in HTML markup (capital V matters). You can also type ⊮ in UTF-8, or use numeric forms when needed.

How It Works
1. Named:⊮ is the HTML5 name for U+22AE → ⊮. Best default in markup.
2. Hex:U+22AE → ⊮ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8878 → ⊮. Same result as hex and named.
4. CSS: use \22AE in content (not an HTML entity). #point::after appends that ⊮ after the paragraph text.
5. Typed / example: paste ⊮ in UTF-8, or write M ⊮ φ. The positive form is ⊩ (⊩).
Pitfalls & Tips
Common mistakes when working with Does Not Force.
Case
Capital V in the name
Write ⊮, not ⊬. Case is part of the HTML5 entity name.
⊩
Positive vs negation
Use ⊩ (⊩) when M forces φ. Use ⊮ (⊮) when it does not.
⊯
Not ⊯
⊯ is U+22AF (⊯) — a different negated turnstile. Do not swap it with ⊮.
CSS vs HTML
Do not mix escapes
\22AE belongs in CSS strings. ⊮ / ⊮ / ⊮ belong in HTML.
Fonts
Math font coverage
Some fonts omit U+22AE. Prefer a font with Mathematical Operators coverage for display.
Semicolon
End references
Always finish with ; — write ⊮, not &nVdash.
Compatibility
Browser Support
Does not force (U+22AE) and its entity forms (⊮, ⊮, ⊮, CSS \\22AE) are supported in all mainstream browsers. Visible glyphs depend on math font coverage.
✓ Universal support

Bottom line: Prefer ⊮ in HTML. Use ⊮ or ⊮ when numeric form is required, and \\22AE only inside CSS content.
Remember
Key Takeaways
Unicode: does not force is U+22AE (decimal 8878) — glyph ⊮.
HTML: prefer ⊮, or use ⊮ / ⊮ / type ⊮.
CSS: use \22AE inside content for generated text.
Meaning:⊮ = does not force — not ⊩ or ⊯.
One line:U+22AE → ⊮ / ⊮ / ⊮ / CSS \22AE / type ⊮.
Frequently Asked Questions
Use ⊮ (named), ⊮ (hex), ⊮ (decimal), type ⊮ directly in UTF-8, or the CSS escape \22AE in content. Prefer ⊮ in normal HTML.
U+22AE (DOES NOT FORCE). Hex 22AE, decimal 8878. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. Use ⊮. Numeric forms ⊮ and ⊮ also work. Note the capital V in nVdash.
Use it in logic and set theory when a structure or condition does not force a statement, for example M ⊮ φ. For the positive relation, use U+22A9 (⊩).
HTML entities (⊮, ⊮, or ⊮) go in markup. The CSS escape \22AE goes in stylesheet strings (usually content on ::before/::after).
No. ⊮ is U+22AE (does not force). ⊩ is U+22A9 (forces). ⊯ is U+22AF — a different negated turnstile.
🤔
Did you know?
Does not force is Unicode U+22AE (decimal 8878) — glyph ⊮ in the Mathematical Operators block. HTML5 names it ⊮. It is the negation of forces ⊩ (⊩). Do not confuse with ⊯ (⊯, U+22AF), which is a different turnstile.
