Left Arrow Through Subset (⥺) is the Supplemental Arrows-B character at Unicode U+297A (LEFTWARDS ARROW THROUGH SUBSET). It combines a leftwards arrow drawn through a subset sign — used in set theory and math notation.
Remember
Character ⥺
Unicode U+297A
Hex entity ⥺
Decimal ⥺
Named entity (none)
CSS escape \297A
Not the same ⥹ (⥹) · ⥻ (⥻)
All of these produce the same glyph: ⥺ (when the font supports U+297A). Prefer numeric entities in HTML; use CSS \297A only in content.
Using Hex Code: ⥺
Using HTML Code: ⥺
Using CSS Entity: ⥺
Typed directly: ⥺
A ⥺ B (subset relation)
How It Works
1. Hex:U+297A → ⥺ in HTML. The browser turns it into ⥺.
2. Decimal: same code point as 10618 → ⥺. Same result as hex.
3. CSS: use \297A in content (not an HTML entity). #point::after appends that ⥺ after the paragraph text.
4. Typed: in UTF-8 you can type ⥺ directly — same visual result when the font supports it.
Pitfalls & Tips
Common mistakes when working with Left Arrow Through Subset.
Named?
No named entity
HTML5 does not define a named entity for U+297A. Use numeric forms.
Name trap
⥹ ≠ U+297A
⥹ is U+2979 (⥹) — subset above a rightwards arrow, not through.
Look-alikes
Not ⥻
U+297B (⥻) is superset above leftwards arrow — a different relation and layout.

Explain the relation
Screen readers may not name this glyph clearly. Add nearby text or aria-label when it carries meaning.
CSS vs HTML
Do not mix escapes
\297A belongs in CSS. ⥺ / ⥺ belong in HTML.
Fonts
Supplemental Arrows coverage
Some fonts omit U+297A. Prefer Segoe UI Symbol, Noto Sans Symbols, or a math-capable face.
