What You'll Learn

How to display the uppercase Y with hook (Ƴ) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+01B3 (LATIN CAPITAL LETTER Y WITH HOOK) in the Latin Extended-B block. It is the capital form paired with lowercase ƴ (U+01B4) and appears in linguistic transcriptions, extended Latin orthographies, and some African language writing systems when uppercase is required.

Render it with Ƴ, Ƴ, or CSS escape \01B3. There is no named HTML entity for this character. In UTF-8 documents you can also type Ƴ directly. This is not plain Y (U+0059)—it is a distinct precomposed Unicode letter with a hook diacritic.

🧠 How It Works

1

Hexadecimal Code

&#x01B3; uses the Unicode hexadecimal value 01B3 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#435; uses the decimal Unicode value 435 to display the same character. A common method when a numeric reference is needed.

3

Direct Character

Type Ƴ directly in HTML when your document uses UTF-8 encoding. There is no named entity for this precomposed letter.

4

CSS Entity

\01B3 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

Same visual result

All methods produce the glyph: Ƴ. Unicode U+01B3 sits in Latin Extended-B. Lowercase equivalent: U+01B4 (ƴ). Do not confuse with plain Y (U+0059).

Use Cases

The uppercase Y hook (Ƴ) is commonly used in:

🎤 Phonetics & Linguistics

Capital form of the y-hook letter in phonetic notation and linguistic transcriptions.

📝 Academic Publications

Linguistics papers, dictionaries, and language documentation using extended Latin letters.

🌍 African Orthographies

Some African language writing systems use y hook as a distinct letter; uppercase Ƴ appears in titles and headings.

🌐 Transliteration

Romanization systems requiring extended Latin letters with hook diacritic.

📚 Language Learning

Courses and reference materials teaching phonetic symbols and extended Latin characters.

⚙ Programmatic HTML

When building HTML from linguistic data, using &#435; or &#x01B3; guarantees correct output.

🎨 CSS generated content

Using \01B3 in the CSS content property to insert Ƴ via pseudo-elements.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type Ƴ directly in UTF-8 source
  • Use numeric references (&#x01B3; or &#435;) when escaping is required
  • Use \01B3 in CSS content when generating the symbol via pseudo-elements
  • Use fonts that support Latin Extended-B characters (U+0180–U+024F)
  • Pair with lowercase ƴ (U+01B4) when both cases are needed in linguistic text

Don’t

  • Confuse Ƴ with plain Y (U+0059) when the hooked letter is required
  • Expect a named HTML entity—none exists for Ƴ
  • Use the incorrect CSS escape \001B3—the correct value is \01B3
  • Put CSS escape \01B3 in HTML text nodes
  • Double-encode numeric references in dynamically generated HTML

Key Takeaways

1

Type Ƴ directly, or use hex/decimal references

&#x01B3; &#435;
2

For CSS stylesheets, use the escape in the content property
