Lowercase c reverse (ɔ) is the IPA Extensions character at Unicode U+0254 (LATIN SMALL LETTER OPEN O). It looks like a reversed c and is used in the International Phonetic Alphabet for the open-mid back rounded vowel, and in many African orthographies.
Remember
Character ɔ
Unicode U+0254
Hex entity ɔ
Decimal ɔ
CSS escape \0254
Named entity (none)
Capital Ɔ (U+0186)
Hex, decimal, CSS, and a typed character all produce the same glyph: ɔ. Prefer ɔ in HTML source when you need an explicit entity.
Using Hex Code: ɔ
Using HTML Code: ɔ
Using CSS Entity: ɔ
IPA: /kɔt/
How It Works
1. Hex:U+0254 → ɔ in HTML. The browser turns it into ɔ.
2. Decimal: same code point as 596 → ɔ. Same result as hex.
3. Named: HTML5 does not define a named entity for this character — use hex or decimal instead.
4. CSS: use \0254 in content (not an HTML entity). #point::after appends that ɔ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with lowercase c reverse (open o).
Named
No &…; shortcut
HTML5 has no named entity for U+0254. Use ɔ or ɔ.
Look-alikes
Not plain o, c, or ↄ
Do not substitute ASCII o/c or Number Forms reversed c (U+2184) when IPA or orthography needs open o.
IPA
Phonetic meaning
In IPA, ɔ marks the open-mid back rounded vowel (as in British English thought for many speakers) — different from plain o.
CSS vs HTML
Do not mix escapes
\0254 belongs in CSS. ɔ / ɔ belong in HTML.
Encoding
Declare UTF-8
If you type ɔ directly, keep <meta charset="UTF-8"> so the file is not misread.
Fonts
Check glyph coverage
Some fonts omit IPA Extensions. Pick a font that includes U+0254 if the glyph is missing.
