Definition

What Is Uppercase U Diaeresis Macron?

Uppercase U Diaeresis Macron (Ǖ) is the Latin Extended-B character at Unicode U+01D5 (LATIN CAPITAL LETTER U WITH DIAERESIS AND MACRON). HTML5 has no named entity — use hex or decimal. Use it for Hanyu Pinyin first-tone ü in capitals and other Latin-script text that needs Ǖ.

Remember

Character     Ǖ
Unicode       U+01D5
Named entity  (none)
Hex entity    &#x01D5;
Decimal       &#469;
CSS escape    \01D5
Not the same  ǖ · &Uuml; · &Umacr; · Ǜ

Hex, decimal, CSS, and a typed character all produce the same glyph: Ǖ. Prefer Ǖ or Ǖ in HTML markup. For the lowercase form see lowercase U diaeresis macron; for fourth tone see uppercase U diaeresis grave.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase U Diaeresis Macron (Ǖ)</title>
  <style>
    #point::after {
      content: "\01D5";
    }
  </style>
</head>
<body>
  <p>Built with Hex: &#x01D5;</p>
  <p>Built with Decimal: &#469;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: Ǖ</p>
  <p lang="zh-Latn">Case pair: Ǖ / ǖ</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex / decimal: U+01D5 → Ǖ or Ǖ. The browser turns either into Ǖ.

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

3. CSS: use \01D5 in content (four hex digits; not an HTML entity). #point::after appends that Ǖ after the paragraph text.

4. Case pair: lowercase is U+01D6 (ǖ) — see lowercase U diaeresis macron. Neither case has a named entity.

Pitfalls & Tips

Common mistakes when working with Uppercase U Diaeresis Macron.

Named

There is no named entity

HTML5 does not define a name for U+01D5. Use Ǖ or Ǖ.

Not plain U umlaut

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

Not plain U macron

U+016A (Ū, &Umacr;) has macron only — no diaeresis. See uppercase U macron.

Tone

Macron ≠ grave for Pinyin tones

First tone uses macron (U+01D5). Fourth tone uses grave (U+01DB). See uppercase U diaeresis grave.

Combining

Prefer the precomposed letter

Use U+01D5 instead of stacking combining marks on U or Ü when the precomposed form is available.

CSS vs HTML

Do not mix escapes

\01D5 belongs in CSS strings. Ǖ / Ǖ belong in HTML.
