Uppercase O center dot (ʘ) is the Unicode character at U+0298 in IPA Extensions. Official name: LATIN LETTER BILABIAL CLICK — an IPA symbol for the bilabial click consonant (visually an O-shaped letter with a center dot).
Remember
Character ʘ
Unicode U+0298
Hex entity ʘ
Decimal ʘ
CSS escape \0298
Named entity (none)
Not the same O · · · Ǒ
Prefer ʘ or ʘ in HTML markup. You can also type ʘ in UTF-8. There is no named entity. Despite the URL, Unicode treats this as the IPA bilabial click, not a Latin capital O with a diacritic.
Using Hex Code: ʘ
Using HTML Code: ʘ
Using CSS Entity: ʘ
Typed directly: ʘ
IPA label: [ʘ]
How It Works
1. Hex:U+0298 → ʘ in HTML. The browser turns it into ʘ.
2. Decimal: same code point as 664 → ʘ. Same result as hex.
3. CSS: use \0298 in content (not an HTML entity). #point::after appends that ʘ after the paragraph text.
4. Typed / IPA: paste ʘ in UTF-8, or write [ʘ] for a short phonetic label.
5. No named entity: HTML5 does not define a name for U+0298 — use numeric references or type the character.
Pitfalls & Tips
