Definition

What Is Uppercase R?

Uppercase R (R) is the Basic Latin character at Unicode U+0052 (LATIN CAPITAL LETTER R). It is the eighteenth letter of the Latin alphabet and a core ASCII character. You can type R directly in HTML, or write a numeric character reference when you need an explicit entity form.

Remember

Character     R
Unicode       U+0052
Hex entity    &#x52;
Decimal       &#82;
CSS escape    \0052
Named entity  (none)
Not the same  r · &Racute; · ℝ

Prefer typing R in normal page text. Use R / R for CSS content, generated markup, or when encoding must be explicit. For the lowercase pair see lowercase r; for R with acute see uppercase R acute.

Try It Yourself

How It Works

1. Hex / decimal: U+0052 → R or R. The browser turns either into R.

2. Typed: most keyboards can type R directly in UTF-8 HTML — usually the simplest option.

3. CSS: use \0052 in content (not an HTML entity). #point::after appends that R after the paragraph text.

4. Example: write normal text with a typed R for everyday content.

Pitfalls & Tips

Common mistakes when working with Uppercase R.

Type it

Prefer the typed character

For body text, type R. Entities are useful for CSS escapes and generated content, not everyday paragraphs.

Named?

No named entity for plain R

HTML5 does not define &R;. Use R / R, or type R.

Not R with acute

U+0154 (Ŕ, &Racute;) is a different letter. See uppercase R acute.

ℝ

Not double-struck R

U+211D (ℝ) is a letterlike math symbol. See uppercase R double struck.

CSS vs HTML

Do not mix escapes

\0052 belongs in CSS strings. R / R belong in HTML.

Case

Case is significant

R (U+0052) and r (U+0072) are different characters. Use the case your content requires.
