Lowercase i with acute (í) is the Latin-1 Supplement character at Unicode U+00ED (LATIN SMALL LETTER I WITH ACUTE). It is common in Spanish, Portuguese, Irish, Catalan, and other languages. HTML5 also defines the named entity í.
Remember
Character í
Unicode U+00ED
Named entity í
Hex entity í
Decimal í

All of these produce the same glyph: í. Prefer í or a pasted í in UTF-8 pages; use numeric or CSS forms when you need them.

How It Works
1. Named:í is the HTML5 named entity for U+00ED. Clearest form in HTML source.
2. Hex:U+00ED → í in HTML. Same glyph as named.
3. Decimal: same code point as 237 → í. Same result.
4. CSS: use \00ED in content (not an HTML entity). #point::after appends that í after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the i acute entity.
Named
Prefer í
HTML5 defines a named entity for this letter — use it for readable HTML.
CSS vs HTML
Do not mix escapes
\00ED belongs in CSS. í / í / í belong in HTML.
Look-alikes
Not i or ı
Plain i is U+0069; dotless ı is U+0131. Acute is a different mark.
Case
í vs Í
Uppercase is U+00CD (Í) — a different code point from U+00ED.
Semicolon
End references
Always finish with ; — write í, not í.
UTF-8
Declare charset
If you paste í directly, serve the page as UTF-8 with <meta charset="UTF-8">.
