Use Cases

The uppercase oi ligature (Ƣ) is commonly used in:

🇮🇪 African orthographies

Historical and contemporary African language writing systems that use oi as a distinct letter (e.g. Gokana).

🔤 Linguistics

Phonetic transcription, dictionaries, and language documentation requiring the single-character oi unit.

📚 Academic publishing

Scholarly papers, Unicode references, and character-set documentation that display Ƣ correctly.

🎨 Typography

Font specimens showcasing Latin Extended-B ligature support in design systems.

🌐 Internationalization

Content targeting locales or languages that require the oi ligature character.

⚙ Programmatic HTML

When building HTML from encoded text, &#418; or &#x01A2; guarantees correct output.

♿ Accessibility

Using U+01A2 ensures assistive technologies interpret the ligature as one character.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type Ƣ directly in UTF-8 source
  • Use numeric references when escaping or generating markup programmatically
  • Use Ƣ when the source text specifies the oi ligature character
  • Choose fonts that support Latin Extended-B (U+0180–U+024F)
  • Distinguish Ƣ from the digraph “OI”, lowercase ƣ, and oe/ou ligatures

Don’t

  • Confuse U+01A2 with the English exclamation “Oi!” (plain letters O + i)
  • Substitute two letters “OI” when Ƣ is the correct encoded character
  • Use padded Unicode notation like U+001A2—the correct value is U+01A2
  • Expect a named HTML entity—none exists for Ƣ
  • Put CSS escape \01A2 in HTML text nodes

Key Takeaways

1

Type Ƣ directly, or use hex/decimal references

&#x01A2; &#418;
2

For CSS stylesheets, use the escape in the content property

\01A2
