Definition

What Is Uppercase R Double Grave?

Uppercase R with double grave (Ȑ) is the Unicode character at U+0210 (LATIN CAPITAL LETTER R WITH DOUBLE GRAVE) in Latin Extended-B — a capital R with two grave marks, used in Slavic linguistics and phonetic transcription.

Remember

Character     Ȑ
Unicode       U+0210
Named entity  (none)
Hex entity    &#x0210;
Decimal       &#528;
CSS escape    \0210
Not the same  ȑ · R · Ȓ · Ř

Prefer Ȑ or Ȑ in HTML markup. You can also type Ȑ in UTF-8. The lowercase pair is ȑ (U+0211). HTML5 has no named entity for either form. Do not confuse this with plain R or R with inverted breve.

Try It Yourself

How It Works

1. Hex / decimal: U+0210 → Ȑ or Ȑ. The browser turns either into Ȑ.

2. Typed: in a UTF-8 document you can paste Ȑ directly — same glyph, no entity.

3. CSS: use \0210 in content (four hex digits; not an HTML entity). #point::after appends that Ȑ after the paragraph text.

4. Case pair: lowercase is U+0211 (ȑ) — see lowercase R double grave.

Pitfalls & Tips

Common mistakes when working with U+0210.

Named?

No named entity

HTML5 does not define a name for Ȑ. Use Ȑ or Ȑ.

Plain R

Not the same as plain R

Plain R (U+0052) has no double grave. Do not substitute it when Ȑ is required.

Not R with inverted breve

U+0212 (Ȓ) is a different accent. See uppercase R inverted breve.

CSS

Use four hex digits in CSS

Write \0210, not a shorter escape that a following digit could extend incorrectly.

Fonts

Need Latin Extended-B coverage

Some fonts omit U+0210. Prefer fonts that cover Latin Extended-B (U+0180–U+024F).

Case

Case is significant

Ȑ (U+0210) and ȑ (U+0211) are different characters. Use the case your content requires.

Compatibility

Browser Support

Uppercase R Double Grave (U+0210) and its entity forms (Ȑ, Ȑ, CSS \\0210) are supported in all mainstream browsers when the page is UTF-8 and the font covers Latin Extended-B.

Bottom line: Prefer Ȑ in HTML text. Use Ȑ as an equivalent, and \\0210 only inside CSS content. Glyph display depends on font coverage.

Remember

Key Takeaways

Unicode: this letter is U+0210 (decimal 528) — glyph Ȑ.
HTML: use Ȑ / Ȑ — no named entity.
CSS: use \0210 (four hex digits) inside content.
Watch out: Ȑ ≠ plain R ≠ inverted breve Ȓ ≠ caron Ř.

One line: U+0210 → Ȑ / Ȑ / CSS \0210 (no named entity).
