Long Right Double Arrow (⟹) is the Supplemental Arrows-A character at Unicode U+27F9 (LONG RIGHTWARDS DOUBLE ARROW). It is a long double-shaft rightwards arrow used in math and diagrams (often for implication).

Named entity ⟹ · ⟹ · ⟹
CSS escape \27F9
Not the same ⟶ (⟶) · ⇒ (⇒)
Named, hex, decimal, CSS, and a typed character all produce the same glyph: ⟹. Prefer ⟹ in HTML source for clarity. Case is significant: ⟹ ≠ ⟶.

How It Works
1. Named:⟹ (aliases ⟹, ⟹) is the clearest HTML form and renders ⟹.
2. Hex:U+27F9 → ⟹ in HTML. Same result as the named entity.
3. Decimal: same code point as 10233 → ⟹. Same result as hex.
4. CSS: use \27F9 in content (not an HTML entity). #point::after appends that ⟹ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with Long Right Double Arrow.
Case
⟹ ≠ ⟶
Capital A selects the double arrow (U+27F9). Lowercase ⟶ is the single long arrow (U+27F6).
Length
⟹ ≠ ⇒
The short right double arrow is ⇒ (U+21D2). Use U+27F9 only when you need the long form.
Aliases
Three named forms
⟹, ⟹, and ⟹ all map to U+27F9. Prefer one style consistently.
CSS vs HTML
Do not mix escapes
\27F9 belongs in CSS. ⟹ / ⟹ / ⟹ belong in HTML.
A11y
Add nearby words
Pair the glyph with labels (for example P ⟹ Q) or use aria-label when it stands alone.
Semicolon
End references
Always finish with ; — write ⟹, not &xrArr.

Key Takeaways
Unicode: this symbol is U+27F9 (decimal 10233).
HTML: prefer ⟹ — or use ⟹ / ⟹.
Use ⟹, ⟹, or ⟹ (named), ⟹ (hex), ⟹ (decimal), or the CSS escape \27F9 in the content property. All render ⟹.
U+27F9 (LONG RIGHTWARDS DOUBLE ARROW). Hex 27F9, decimal 10233. It belongs to Supplemental Arrows-A (U+27F0–U+27FF).
Yes. ⟹, ⟹, and ⟹ are named HTML5 entities for ⟹ and are supported in all modern browsers.
Use it for implication, math mappings, flowcharts, and diagrams that need a long rightwards double arrow. Prefer ⟹ for readable source.
HTML entities (⟹, ⟹, or ⟹) go in markup. The CSS escape \27F9 is used in stylesheets (usually in the content property of ::before/::after). Both render ⟹.
No. ⟶ is the long single right arrow (U+27F6). ⇒ is the short right double arrow (U+21D2, ⇒). ⟹ (U+27F9) is the long rightwards double arrow.

Did you know?
Long Right Double Arrow is Unicode U+27F9 (decimal 10233) — LONG RIGHTWARDS DOUBLE ARROW in Supplemental Arrows-A. HTML5 provides ⟹, ⟹, and ⟹ — all render ⟹. Prefer ⟹ for readable source. Case matters: ⟶ is the single arrow (⟶), ⟹ is the double (⟹).
