How It Works
1. Hex:U+01C3 → ǃ in HTML. The browser turns it into ǃ.
2. Decimal: same code point as 451 → ǃ. Same result as hex.
3. CSS: use \01C3 in content (not an HTML entity). #point::after appends that ǃ after the paragraph text.
4. Typed ǃ: fine in UTF-8 HTML. All four lines show the same letter.
Pitfalls & Tips
Common mistakes when working with the retroflex click.
Named?
No named entity
HTML5 does not define a named entity for ǃ. Use ǃ or ǃ.
Look-alikes
Not ASCII !
Do not substitute ! (U+0021) for ǃ in IPA. They look similar but are different characters.
Clicks
Not alveolar ǂ
Alveolar click ǂ is U+01C2. Retroflex ǃ is U+01C3 — pick the symbol that matches the sound.
CSS vs HTML
Do not mix escapes
\01C3 belongs in CSS. ǃ / ǃ belong in HTML.
Encoding
Declare UTF-8
If you type ǃ directly, keep <meta charset="UTF-8"> so the file is not misread.
Semicolon
End references
Always finish with ; — write ǃ, not ǃ.
