What You'll Learn

How to display the lowercase u with macron (ū) in HTML using named entity, hexadecimal, decimal, and CSS escape methods. This character is U+016B in the Latin Extended-A block. It combines the letter u with a macron (overline) indicating a long vowel and is a distinct letter in Latvian (e.g. būt, mūs) and used in Māori and linguistic notation.

Render it with ū, ū, ū, or CSS escape \016B. The named entity ū is often the most readable option in HTML source.

🧠 How It Works

1

Hexadecimal Code

&#x016B; uses the Unicode hexadecimal value 016B to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#363; uses the decimal Unicode value 363 to display the same character. A common method when a numeric reference is needed.

3

Named Entity

&umacr; is the standard named entity for ū—readable in source HTML and part of the HTML entity set for Latin Extended-A characters.

CSS Entity

\016B is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

Same visual result

All four methods produce the glyph: ū. Unicode U+016B sits in Latin Extended-A. Uppercase equivalent: U+016A (&Umacr;). Do not confuse with ǖ (u diaeresis macron) or ŭ (u breve).

Use Cases

The lowercase u macron (ū) is commonly used in:

🇩🇻 Latvian

Essential letter in Latvian orthography (būt, mūs, dūra) for websites, news, and localized UI.

🇳🇿 Meori

Long vowel u in Meori words and te reo Meori web content and educational materials.

🌐 Internationalization

Multilingual websites, CMS content, and email templates requiring correct extended Latin characters.

📝 Linguistics & Phonology

Phonetic transcription indicating long u with macron marking.

📚 Language Learning

Courses, dictionaries, and grammar resources teaching macron-accented u.

♿ Accessibility

Using the correct character (U+016B) with appropriate lang attributes helps screen readers pronounce text correctly.

⚙ Programmatic HTML

When escaping user input or generating HTML, &umacr; ensures safe, correct output.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type ū directly in UTF-8 source
  • Use &umacr; in HTML when possible for readability
  • Use numeric references (&#x016B; or &#363;) when escaping is required
  • Use \016B in CSS content when generating the symbol via pseudo-elements
  • Distinguish ū from ǖ (u diaeresis macron) and ŭ (u breve)

Don’t

  • Confuse ū with ǖ (Pinyin u diaeresis macron) or plain u
  • Use the old incorrect CSS escape \0016B—the correct value is \016B
  • Put CSS escape \016B in HTML text nodes
  • Substitute plain u when the macron letter is required (e.g. Latvian būt)
  • Double-encode numeric references in dynamically generated HTML

Key Takeaways

1

Three HTML references plus a named entity all render ū

&#x016B; &#363; &umacr;
2

For CSS stylesheets, use the escape in the content property
