How It Works
1. Hex:U+0223 → ȣ in HTML. The browser turns it into ȣ.
2. Decimal: same code point as 547 → ȣ. Same result as hex.
3. CSS: use \0223 in content (not an HTML entity). #point::after appends ȣ.
4. Typed: paste ȣ in a UTF-8 document for orthographic or linguistic text. There is no named entity — numeric form is required when you need an entity.
Pitfalls & Tips
Common mistakes when working with Latin small letter ou.
Named?
No named entity
HTML5 does not define a named entity for U+0223. Use ȣ or ȣ.
ou
Not two letters
Typing ou is two Basic Latin characters. ȣ is one Extended-B letter — different code points and sorting behavior.
œ
Not œ
œ is the French oe ligature. ȣ is Latin small letter ou — do not swap them.
Fonts
Need Extended-B coverage
Some fonts omit Latin Extended-B. Prefer a font that includes U+0223 for reliable glyphs.
CSS
Pad the CSS escape
Prefer \0223 (four hex digits). A short \223 can swallow the next hex digit if one follows immediately.
CSS vs HTML
Do not mix escapes
\0223 belongs in CSS strings. ȣ / ȣ belong in HTML.
Semicolon
End references
Always finish entities with ; — write ȣ, not ȣ.
