Not the same ǐ · Î · Ĭ
Prefer Ǐ or Ǐ in HTML markup. You can also type Ǐ in UTF-8. The lowercase pair is ǐ (U+01D0). HTML5 has no named entity for either form.
Using Hex Code: Ǐ
Using HTML Code: Ǐ
Using CSS Entity: Ǐ
Typed directly: Ǐ
Pinyin: Ǐ
How It Works
1. Hex:U+01CF → Ǐ in HTML. Preferred numeric form when you need an entity.
2. Decimal: same code point as 463 → Ǐ. Same glyph as hex.
3. CSS: use \01CF in content (not an HTML entity). #point::after appends that Ǐ after the paragraph text.
4. Typed / Pinyin: paste Ǐ in UTF-8, or mark latinized Chinese with lang="zh-Latn".
5. No named entity: HTML5 does not define a name for U+01CF — use numeric references or type the character. Ě is Ě, not Ǐ.
Pitfalls & Tips
Common mistakes when working with U+01CF.
Named
No named HTML entity
There is no &Icaron;. Use Ǐ or Ǐ. Ě is Czech Ě (U+011A).
vs Î
Not a circumflex
Î (Î) has a ˆ mark. The caron is a háček (∨) — do not swap them.
vs Ĭ
Not a breve
Ĭ (&Ibreve;) has a short curve (˘). Breve and caron are different diacritics.
Czech
Czech uses Ě, not Ǐ
Czech háček on E is Ě (Ě). Do not use U+01CF for Czech text.
Fonts
Needs Extended-B coverage
Some UI fonts omit Latin Extended-B. Prefer a stack that includes Extended-B if the glyph must always show.
CSS vs HTML
Do not mix escapes
\01CF belongs in CSS strings. Ǐ / Ǐ belong in HTML.
