What Is the Lowercase I Tilde Entity?

Lowercase i tilde (ĩ) is the Latin Extended-A character at Unicode U+0129 (LATIN SMALL LETTER I WITH TILDE). It is the letter i with a tilde (~) above — used in Kikuyu and older Greenlandic orthography.

Remember
Character     ĩ
Unicode       U+0129
Named entity  ĩ
Hex entity    ĩ
Decimal       ĩ
CSS escape    \0129
Capital       Ĩ (Ĩ)

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ĩ. Prefer ĩ in HTML source for clarity.

Four ways to produce ĩ in a single document.

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Lowercase I Tilde (&itilde;)</title>
  <style>
    #point::after {
      content: "\0129";
    }
  </style>
</head>
<body>
  <p>Using Named Entity: &itilde;</p>
  <p>Using Hex Code: &#x129;</p>
  <p>Using HTML Code: &#297;</p>
  <p id="point">Using CSS Entity: </p>
  <p lang="ki">Kikuyu: G&itilde;kũyũ</p>
</body>
</html>

How It Works

1. Named: &itilde; is the clearest HTML form and renders ĩ.

2. Hex: U+0129 → &#x129; in HTML. Same result as the named entity.

3. Decimal: same code point as 297 → &#297;. Same result as hex.

4. CSS: use \0129 in content (not an HTML entity). #point::after appends that ĩ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with lowercase i tilde.

Case

&itilde; ≠ &Itilde;

Named entities are case-sensitive. Lowercase is ĩ; uppercase is Ĩ.

Look-alikes

Not ï or ñ

Tilde sits above the letter. Do not confuse &itilde; with &iuml; (ï) or &ntilde; (ñ).

Compose

Prefer precomposed

Use &itilde; instead of i plus combining tilde (U+0303) when the precomposed form exists.

CSS vs HTML

Do not mix escapes

\0129 belongs in CSS. &itilde; / &#x129; / &#297; belong in HTML.

Encoding

Declare UTF-8

If you type ĩ directly, keep <meta charset="UTF-8"> so the file is not misread.

Semicolon

End references

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

Browser Support

Lowercase i tilde (U+0129) and its entity forms (&itilde;, &#x129;, &#297;, CSS \\0129) are supported in all modern browsers.

✓ Universal encoding

Lowercase I Tilde (&itilde;)

Encode with named, hex, decimal, or CSS escape — or type ĩ directly in UTF-8 HTML.

Key Takeaways

  • Unicode: this character is U+0129 (decimal 297).
  • HTML: prefer &itilde; — or use &#x129; / &#297;.
  • CSS: use \0129 inside content for generated text.
  • Watch out: &itilde; ≠ &Itilde; ≠ &iuml;.

One line: U+0129 → &itilde; / &#x129; / &#297; / CSS \0129.

Frequently Asked Questions

Use &itilde; (named), &#x129; (hex), &#297; (decimal), or the CSS escape \0129 in the content property. All render ĩ. Prefer &itilde; in HTML source.
U+0129 (LATIN SMALL LETTER I WITH TILDE). Hex 129, decimal 297. It belongs to Latin Extended-A (U+0100–U+017F).
Yes. &itilde; is the HTML5 named entity for ĩ. The capital form is &Itilde; (Ĩ, U+0128) — names are case-sensitive.
Use it for Kikuyu (Gĩkũyũ), older Greenlandic orthography, language materials, and other internationalized content that needs ĩ.
HTML entities (&itilde;, &#297;, or &#x129;) go in markup. The CSS escape \0129 is used in stylesheets (usually in the content property of ::before/::after). Both render ĩ.
Visually similar, but U+0129 is a precomposed character. Combining tilde is U+0303 after a base letter. Prefer the precomposed &itilde; when available.
