Uppercase R Caron (Ř) is the Latin Extended-A character at Unicode U+0158 (LATIN CAPITAL LETTER R WITH CARON). HTML5 names it Ř. Use it for Czech, Slovak, and other Latin-script text that needs Ř (háček on R).

Not the same ř (ř) · R · Ŕ
Named, hex, decimal, CSS, and a typed character all produce the same glyph: Ř. Prefer Ř or Ř in HTML markup. For the lowercase form see ř; for R with acute see uppercase R acute.

How It Works
1. Named:Ř is the HTML5 name for U+0158 → Ř (case-sensitive: capital R).
2. Hex / decimal:Ř or Ř insert the same code point.
3. Typed: in a UTF-8 document you can paste Ř directly — same glyph, no entity.
4. CSS: use \0158 in content (not an HTML entity). #point::after appends that Ř after the paragraph text.
5. Czech:lang="cs" marks the language; Řeka spells Řeka (river).
Pitfalls & Tips
Common mistakes when working with Uppercase R Caron.
Case
Named entity is case-sensitive
Ř is Ř. ř is ř. Do not mix them.
Plain R
Not the same as plain R
Plain R (U+0052) has no caron. Do not substitute it when Ř is required for Czech spelling.
Ŕ
Not R with acute
U+0154 (Ŕ, Ŕ) uses an acute, not a caron. See uppercase R acute.
Combining
Prefer the precomposed letter
Use U+0158 instead of R + combining caron (U+030C) when the precomposed form is available.
CSS vs HTML
Do not mix escapes
\0158 belongs in CSS strings. Ř / Ř / Ř belong in HTML.
Fonts
Need Latin Extended-A coverage
Some fonts omit U+0158. Prefer fonts that cover Latin Extended-A (U+0100–U+017F).
