Lowercase b stroke (ƀ) is the Latin Extended-B character at Unicode U+0180 (LATIN SMALL LETTER B WITH STROKE). It is also called barred b — the letter b with a horizontal stroke — used in Americanist phonetic transcription and linguistic notation.
Remember
Character ƀ
Unicode U+0180
Hex entity ƀ
Decimal ƀ
CSS escape \0180
Named entity (none)
Capital Ƀ (U+0243)
Hex, decimal, CSS, and a typed character all produce the same glyph: ƀ. Prefer ƀ in HTML source when you need an explicit entity.
Using Hex Code: ƀ
Using HTML Code: ƀ
Using CSS Entity: ƀ
Case pair: Ƀ / ƀ
How It Works
1. Hex:U+0180 → ƀ in HTML. The browser turns it into ƀ.
2. Decimal: same code point as 384 → ƀ. Same result as hex.
3. Named: HTML5 does not define a named entity for this character — use hex or decimal instead.
4. CSS: use \0180 in content (not an HTML entity). #point::after appends that ƀ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with lowercase b stroke.
Named
No &…; shortcut
HTML5 has no named entity for U+0180. Use ƀ or ƀ.
Look-alikes
Not plain b or b hook
Do not substitute ASCII b or IPA ɓ when barred b is required for transcription accuracy.
Name
Stroke through the stem
The stroke is a horizontal bar through the letter — also called barred b in Americanist phonetics.
CSS vs HTML
Do not mix escapes
\0180 belongs in CSS. ƀ / ƀ belong in HTML.
Encoding
Declare UTF-8
If you type ƀ directly, keep <meta charset="UTF-8"> so the file is not misread.
Fonts
Check glyph coverage
Some fonts omit Latin Extended-B. Pick a font that includes U+0180 if the glyph is missing.

Key Takeaways
Unicode: this character is U+0180 (decimal 384).
HTML: prefer ƀ — or use ƀ (no named entity).
CSS: use \0180 inside content for generated text.
Watch out:ƀ ≠ plain b ≠ IPA hook (ɓ) ≠ capital Ƀ.
One line:U+0180 → ƀ / ƀ / CSS \0180 (no named entity).
