Definition

What Is the Lowercase R Caron Entity?

Lowercase r caron (ř) is the Latin Extended-A character at Unicode U+0159 (LATIN SMALL LETTER R WITH CARON). It is the letter r with a caron (háček) — used in Czech, Slovak, and related orthographies.

Remember

Character     ř
Unicode       U+0159
Named entity  &rcaron;
Hex entity    &#x159;
Decimal       &#345;
CSS escape    \0159
Capital       &Rcaron; (Ř)

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ř. Prefer &rcaron; in HTML source for clarity.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Lowercase R Caron (&rcaron;)</title>
  <style>
    #point::after {
      content: "\0159";
    }
  </style>
</head>

  <p>Using Named Entity: &rcaron;</p>
  <p>Using Hex Code: &#x159;</p>
  <p>Using HTML Code: &#345;</p>

  <p lang="cs">Čeština: &rcaron;eka, Dvo&rcaron;&aacute;k</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: &rcaron; is the clearest HTML form and renders ř.

2. Hex: U+0159 → ř in HTML. Same result as the named entity.

3. Decimal: same code point as 345 → ř. Same result as hex.

4. CSS: use \0159 in content (not an HTML entity). #point::after appends that ř after the paragraph text.

Pitfalls & Tips

Common mistakes when working with lowercase r caron.

Case

`&rcaron;` ≠ `&Rcaron;`

Named entities are case-sensitive. Lowercase is ř; uppercase is Ř.

Look-alikes

Not plain `r` or acute

Do not substitute ASCII r or r acute (&racute;) when Czech or Slovak spelling requires the caron.

Compose

Prefer precomposed

Use &rcaron; instead of stacking combining caron (U+030C) on r when the precomposed form exists.

CSS vs HTML

Do not mix escapes

\0159 belongs in CSS. &rcaron; / ř / ř belong in HTML.

Encoding

Declare UTF-8

If you type ř directly, keep <meta charset="UTF-8"> so the file is not misread.

Semicolon

End references

Always finish with ; — write &rcaron;, not &rcaron.
