How It Works

1. Hex: U+2951 → &#x2951; in HTML. Preferred numeric form when you need an entity.

2. Decimal: same code point as 10577 → &#10577;. Same glyph as hex.

3. CSS: use \2951 in content (not an HTML entity). #point::after appends that ⥑ after the paragraph text.

4. Typed / notation: paste ⥑ in UTF-8, or write f &#x2951; g for a short math label.

5. No named entity: HTML5 does not define a name for U+2951 — use numeric references or type the character.

Pitfalls & Tips

Common mistakes when working with U+2951.

vs ⥍

Barb direction matters

⥍ (U+294D) has a right barb on the down harpoon. ⥑ has left barbs on both — do not swap them in diagrams.

vs ⥮

Not the stacked left form

⥮ (U+296E) is a different layout of up/down left harpoons. Check the code point when matching a printed chart.

Named

No named HTML entity

There is no short name like &ulharpoon; for U+2951. Use &#x2951; or &#10577;.

Fonts

Needs Supplemental Arrows-B coverage

Many UI fonts omit these harpoons. Prefer a stack that includes a math or symbols font if the glyph must always show.

CSS vs HTML

Do not mix escapes

\2951 belongs in CSS strings. &#x2951; / &#10577; belong in HTML.

A11y

Name the relation in context

Screen readers may announce this unevenly. Prefer nearby plain-language text such as “up-down left harpoon” when the symbol carries meaning.
