Uppercase I circumflex (Î) is the Unicode character at U+00CE in Latin-1 Supplement. Official name: LATIN CAPITAL LETTER I WITH CIRCUMFLEX — a capital I with a circumflex accent (ˆ), used in French and Romanian.
Remember
Character Î
Unicode U+00CE
Named entity Î (capital I)
Hex entity Î
Decimal Î
CSS escape \00CE
Not the same î · Ǐ · Ĭ
Prefer Î in HTML markup — the capital I in the name matters. Numeric forms and typing Î in UTF-8 also work. For the lowercase letter, use î (î).
Using Named Entity: Î
Using Hex Code: Î
Using HTML Code: Î
Using CSS Entity: Î
Typed directly: Î
Word: ÎLE
How It Works
1. Named:Î (capital I) is the clearest HTML form for U+00CE. Lowercase î is a different character (î).
2. Hex:U+00CE → Î in HTML. Same glyph as the named entity.
3. Decimal: same code point as 206 → Î. Same glyph as hex and named.
4. CSS: use \00CE in content (not an HTML entity). #point::after appends that Î after the paragraph text.
5. Typed / word: paste Î in UTF-8, or build French words like ÎLE with lang="fr".
Pitfalls & Tips
Common mistakes when working with U+00CE.
Case
Î ≠ î
Î → Î (capital). î → î (lowercase). Entity names are case-sensitive.
vs Ǐ
Not a caron
Ǐ has a háček (∨). Circumflex is ˆ — do not use Î when you need Ǐ.
vs Ĭ
Not a breve
Ĭ (&Ibreve;) has a short curve (˘). Different diacritic and code point.
Encoding
Keep UTF-8 declared
Latin-1 letters display reliably with <meta charset="UTF-8">. Prefer named entities when the source file encoding is uncertain.
CSS vs HTML
Do not mix escapes
\00CE belongs in CSS strings. Î / Î / Î belong in HTML.
A11y
Use real language context
When Î appears in real words (e.g. French or Romanian), keep surrounding text and lang accurate so screen readers get useful context.

Remember
Key Takeaways
Unicode: uppercase I circumflex is U+00CE (decimal 206) — glyph Î.
HTML: prefer Î (capital I) — also Î / Î.
CSS: use \00CE inside content for generated text.
Meaning:Î is capital circumflex — not î (î), not Ǐ (caron).
Use Î (named), Î (hex), Î (decimal), type Î directly in UTF-8, or the CSS escape \00CE in content. Prefer Î in normal HTML.
U+00CE (LATIN CAPITAL LETTER I WITH CIRCUMFLEX). Hex CE, decimal 206. It belongs to Latin-1 Supplement (U+0080–U+00FF).
Yes. Use Î (capital I). Numeric forms Î and Î also work. Note: î (lowercase) is a different letter (î).
No. Î is U+00CE (Î, capital circumflex). î is U+00EE (î). Ǐ is U+01CF (caron / háček, no named entity).
Use it for French, Romanian, and other languages that need Î in titles, names, and uppercase text — not as a substitute for caron Ǐ or breve Ĭ.
HTML entities (Î, Î, or Î) go in markup. The CSS escape \00CE goes in stylesheet strings (usually content on ::before/::after).
