Definition

What Is Uppercase U Diaeresis Caron?

Uppercase U Diaeresis Caron (Ǚ) is the Latin Extended-B character at Unicode U+01D9 (LATIN CAPITAL LETTER U WITH DIAERESIS AND CARON). HTML5 has no named entity — use hex or decimal. Use it for Hanyu Pinyin third-tone ü in capitals and other Latin-script text that needs Ǚ.

Remember

Character     Ǚ
Unicode       U+01D9
Named entity  (none)
Hex entity    &#x01D9;
Decimal       &#473;
CSS escape    \01D9
Not the same  ǚ · &Uuml; · Ǘ · Ǔ

Hex, decimal, CSS, and a typed character all produce the same glyph: Ǚ. Prefer Ǚ or Ǚ in HTML markup. For the lowercase form see lowercase U diaeresis caron; for second tone see uppercase U diaeresis acute.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase U Diaeresis Caron (Ǚ)</title>
  <style>
    #point::after {
      content: "\01D9";
    }
  </style>
</head>
<body>
  <p>Built with Hex: &#x01D9;</p>
  <p>Built with Decimal: &#473;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: Ǚ</p>
  <p lang="zh-Latn">Case pair: Ǚ / ǚ</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex / decimal: U+01D9 → Ǚ or Ǚ. The browser turns either into Ǚ.

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

3. CSS: use \01D9 in content (four hex digits; not an HTML entity). #point::after appends that Ǚ after the paragraph text.

4. Case pair: lowercase is U+01DA (ǚ) — see lowercase U diaeresis caron. Neither case has a named entity.

Pitfalls & Tips

Common mistakes when working with Uppercase U Diaeresis Caron.

Named

There is no named entity

HTML5 does not define a name for U+01D9. Use Ǚ or Ǚ.

Not plain U umlaut

U+00DC (Ü, Ü) has diaeresis only — no caron. See uppercase U umlaut.

Tone

Caron ≠ acute for Pinyin tones

Third tone uses caron (U+01D9). Second tone uses acute (U+01D7). See uppercase U diaeresis acute.

Caron

Not U with caron alone

U+01D3 (Ǔ) has a caron but no diaeresis. See uppercase U caron.

Combining

Prefer the precomposed letter

Use U+01D9 instead of stacking combining marks on U or Ü when the precomposed form is available.

CSS vs HTML

Do not mix escapes

\01D9 belongs in CSS strings. Ǚ / Ǚ belong in HTML.

Compatibility

Uppercase U Diaeresis Caron (U+01D9) and its entity forms (Ǚ, Ǚ, CSS \\01D9) are supported in all mainstream browsers when the page is UTF-8 and the font covers Latin Extended-B.
