🧠 How It Works

1

Named Entity

&Itilde; is the standard named entity for Ĩ—readable in source HTML and part of the HTML5 entity set.

HTML markup
2

Hexadecimal Code

&#x128; uses the Unicode hexadecimal value 128 to display the character. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#296; uses the decimal Unicode value 296 to display the same character. A common method for Latin Extended-A characters.

4

CSS Entity

\128 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: Ĩ. Unicode U+0128 sits in Latin Extended-A. It decomposes to I (U+0049) + combining tilde (U+0303). Lowercase equivalent: U+0129 (&itilde;). Do not confuse with Ñ (N with tilde).

✅

Use Cases

The uppercase I tilde (Ĩ) is commonly used in:

🇰🇪 Kikuyu

Capital Ĩ in GĨkũyũ and other Kikuyu words and proper nouns at sentence start.

🇵🇾 Guarani

Guarani language content where nasalized vowels include capital I with tilde.

🔤 Language learning

Textbooks, dictionaries, and resources teaching Kikuyu, Guarani, and other tilde-using languages.

📝 Names & forms

Correctly capturing capitalized Kikuyu and Guarani names in inputs and databases.

🗣 Linguistics

Transliteration systems and notation using the tilde for nasalization or other features.

🌐 Internationalization

Multilingual websites serving audiences that require proper tilde diacritics on capital I.

♿ Accessibility

Accurate diacritics improve clarity for readers and assistive technologies.

💡 Best Practices

Do

  • Use &Itilde; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ĩ directly in UTF-8 source
  • Set lang attributes (e.g. lang="ki") for correct pronunciation
  • Use fonts that support Latin Extended-A characters
  • Distinguish Ĩ (i tilde) from Ñ (N tilde) and plain I

Don’t

  • Substitute plain I when Ĩ is required for correct spelling
  • Confuse Ĩ (i tilde) with Ñ (N tilde) or ĩ (lowercase)
  • Put CSS escape \128 in HTML text nodes
  • Use padded Unicode notation like U+00128—the correct value is U+0128
  • Use \00128 in CSS—the correct escape is \128

Key Takeaways

1

Four references render Ĩ; named entity is most readable

&#x128; &#296; &Itilde;
2

For CSS stylesheets, use the escape in the content property

\128
