What Is the Lowercase U Macron Entity?

Lowercase u with macron (ū) is the Latin Extended-A character at Unicode U+016B (LATIN SMALL LETTER U WITH MACRON). A horizontal bar sits above the letter, often marking a long vowel. Common in Latvian and Māori. HTML5 defines the named entity ū.

Remember
Character     ū
Unicode       U+016B
Named entity  ū
Hex entity    ū
Decimal       ū
CSS escape    \016B

All of these produce the same glyph: ū. Prefer ū or a pasted ū in UTF-8 pages; use numeric or CSS forms when you need them.

How It Works

1. Named: &umacr; is the HTML5 named entity for U+016B. Clearest form in HTML source.

2. Hex: U+016B → &#x016B; in HTML. Same glyph as named.

3. Decimal: same code point as 363 → &#363;. Same result.

4. CSS: use \016B in content (not an HTML entity). #point::after appends that ū after the paragraph text.

Pitfalls & Tips

Common mistakes when working with the u macron entity.

Named

Prefer &umacr;

HTML5 defines a named entity for this letter — use it for readable HTML.

CSS vs HTML

Do not mix escapes

\016B belongs in CSS. &umacr; / &#x016B; / &#363; belong in HTML.

Look-alikes

Not u or ǖ

Plain u is U+0075; ǖ adds diaeresis too. Macron-only is U+016B.

Case

ū vs Ū

Uppercase is U+016A (&Umacr;) — a different code point from U+016B.

Semicolon

End references

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

UTF-8

Declare charset

If you paste ū directly, serve the page as UTF-8 with <meta charset="UTF-8">.

Bottom line: Prefer &umacr; or a pasted ū in UTF-8 text. Use &#x016B; / &#363; when a numeric form is required, and \\016B only inside CSS content.

Key Takeaways

  • Unicode: u with macron is U+016B (decimal 363), Latin Extended-A.
  • HTML: prefer &umacr;, or use &#x016B; / &#363;.
  • CSS: use \016B inside content for generated text.
  • Use: Latvian / long vowels — not the same as plain u or ǖ.

One line: U+016B → &umacr;, or &#x016B; / &#363; / CSS \016B.

Frequently Asked Questions
