Oi ligature (ƣ) is the Unicode character at U+01A3 in the Latin Extended-B block. Official name: LATIN SMALL LETTER OI. It is a single precomposed letter — not the English interjection “Oi!”

Prefer typing ƣ in UTF-8 when the orthography requires it. Use numeric entities when encoding must be explicit. Uppercase form: Ƣ (U+01A2).

Typed directly: ƣ
How It Works
1. Hex:U+01A3 → ƣ in HTML. The browser turns it into ƣ.
2. Decimal: same code point as 419 → ƣ. Same result as hex.
3. CSS: use \01A3 in content (not an HTML entity). #point::after appends that ƣ after the paragraph text.
4. Typed: paste ƣ in UTF-8 when the page charset is UTF-8. There is no &oi; named entity.
Pitfalls & Tips
Common mistakes when working with Oi Ligature.
Named?
No &oi;
HTML5 does not define a named entity for U+01A3. Use numeric forms.
Oi!
Not the English interjection
“Oi!” is ordinary O + i. Do not replace it with ƣ.
oi
Not two letters
Typing oi is two code points. The ligature ƣ is one character when the orthography requires it.
CSS vs HTML
Do not mix escapes
\01A3 belongs in CSS strings. ƣ / ƣ belong in HTML.
Fonts
Check Latin Extended-B
Some fonts omit U+01A3. Prefer a font with Latin Extended-B coverage for display.
Semicolon
End references
Always finish with ; — write ƣ, not ƣ.
