Definition

What Is the Turned Greek Small Letter Iota Entity?

Turned Greek Small Letter Iota (℩) is the Letterlike Symbols character at Unicode U+2129 (TURNED GREEK SMALL LETTER IOTA). It is a turned form of iota used mainly in phonetic and linguistic notation.

Remember

Character     ℩
Unicode       U+2129
Hex entity    &#x2129;
Decimal       &#8489;
Named entity  &iiota;
CSS escape    \2129

Try It Yourself

How It Works

1. Hex: U+2129 → ℩ in HTML. The browser turns it into ℩.

2. Decimal: same code point as 8489 → ℩. Same result as hex.

3. Named: &iiota; is the HTML5 name for this character.

4. CSS: use \2129 in content (not an HTML entity). #point::after appends that ℩ after the paragraph text.

End references
