Uppercase I acute (Í) is the Unicode character at U+00CD in Latin-1 Supplement. Official name: LATIN CAPITAL LETTER I WITH ACUTE — a capital I with an acute accent (´ shape), used in Spanish, Portuguese, and Catalan.
Remember
Character Í
Unicode U+00CD
Named entity Í (capital I)
Hex entity Í
Decimal Í
CSS escape \00CD
Not the same í · Ì · Î
Prefer Í in HTML markup — the capital I in the name matters. Numeric forms and typing Í in UTF-8 also work. For the lowercase letter, use í (í).
Using Named Entity: Í
Using Hex Code: Í
Using HTML Code: Í
Using CSS Entity: Í
Typed directly: Í
Word: ÍNDICE
How It Works
1. Named:Í (capital I) is the clearest HTML form for U+00CD. Lowercase í is a different character (í).
2. Hex:U+00CD → Í in HTML. Same glyph as the named entity.
3. Decimal: same code point as 205 → Í. Same glyph as hex and named.
4. CSS: use \00CD in content (not an HTML entity). #point::after appends that Í after the paragraph text.
5. Typed / word: paste Í in UTF-8, or build Spanish words like ÍNDICE with lang="es".
Pitfalls & Tips
Common mistakes when working with U+00CD.
Case
Í ≠ í
Í → Í (capital). í → í (lowercase). Entity names are case-sensitive.
vs Ì
Not a grave
Ì (Ì) slopes the other way. Acute rises to the right; grave falls to the left.
vs Î
Not a circumflex
Î (Î) has a ˆ mark. Do not use Í when the language needs Î.
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
\00CD belongs in CSS strings. Í / Í / Í belong in HTML.
A11y
Use real language context
When Í appears in real words (e.g. Spanish), keep surrounding text and lang accurate so screen readers get useful context.

Remember
Key Takeaways
Unicode: uppercase I acute is U+00CD (decimal 205) — glyph Í.
HTML: prefer Í (capital I) — also Í / Í.
CSS: use \00CD inside content for generated text.
Meaning:Í is capital acute — not í (í), not Ì (grave).
Use Í (named), Í (hex), Í (decimal), type Í directly in UTF-8, or the CSS escape \00CD in content. Prefer Í in normal HTML.
U+00CD (LATIN CAPITAL LETTER I WITH ACUTE). Hex CD, decimal 205. It belongs to Latin-1 Supplement (U+0080–U+00FF).
Yes. Use Í (capital I). Numeric forms Í and Í also work. Note: í (lowercase) is a different letter (í).
No. Í is U+00CD (Í, capital acute). í is U+00ED (í). Ì is U+00CC (Ì, grave accent).
Use it for Spanish, Portuguese, Catalan, and other languages that need Í in titles, names, and uppercase text — not as a substitute for grave Ì or circumflex Î.
HTML entities (Í, Í, or Í) go in markup. The CSS escape \00CD goes in stylesheet strings (usually content on ::before/::after).
