Lowercase o with ogonek (ǫ) is the Unicode character at U+01EB in Latin Extended-B. Official name: LATIN SMALL LETTER O WITH OGONEK — the letter o with a little hook (ogonek) below. Used in Navajo and some linguistic texts.
Remember
Character ǫ
Unicode U+01EB
Hex entity ǫ
Decimal ǫ
CSS escape \01EB
Named entity (none)
Capital Ǫ (U+01EA)
Not the same o · ę (ę) · ą (ą)
Prefer ǫ or ǫ in HTML when you need an entity. You can also type ǫ in a UTF-8 document.
Built with Hex: ǫ
Built with Decimal: ǫ
Built with CSS: ǫ
Typed: ǫ
Navajo: ǫ
How It Works
1. Hex:U+01EB → ǫ in HTML. The browser turns it into ǫ.
2. Decimal: same code point as 491 → ǫ. Same result as hex.
3. CSS: use \01EB in content (not an HTML entity). #point::after appends ǫ.
4. Typed: paste ǫ in a UTF-8 document for Navajo or linguistic text. There is no &oogonek; — numeric form is required when you need an entity.
Pitfalls & Tips
Common mistakes when working with lowercase o with ogonek.
Named?
No &oogonek;
HTML5 has ą and ę, but not for o. Use ǫ or ǫ.
ę
Not ę
ę is e with ogonek. ǫ is o with ogonek — different letters.
Look-alikes
Not cedilla
A cedilla (¸) and an ogonek (˛) look similar but are different diacritics. ǫ specifically uses the ogonek.
Fonts
Need Extended-B coverage
Some fonts omit Latin Extended-B. Prefer a font that includes U+01EB for reliable glyphs.
CSS
Pad the CSS escape
Prefer \01EB (four hex digits). A short \1EB can swallow the next hex digit if one follows immediately.
CSS vs HTML
Do not mix escapes
\01EB belongs in CSS strings. ǫ / ǫ belong in HTML.
Semicolon
End references
Always finish entities with ; — write ǫ, not ǫ.
