U00ED

U+00CD, Latin Capital Letter I with Acute, is a letter used in several Latin-script languages. Its uppercase form is Í and its lowercase form is í. It belongs to the Latin-1 Supplement block in Unicode and has the official name LATIN CAPITAL LETTER I WITH ACUTE. The code point is U+00CD (decimal 205).

In text encoding, Í can be represented in Unicode, and in HTML it can be encoded as Í or Í. In UTF-8, the character is encoded as the two-byte sequence C3 8D. The character is case–paired with í (U+00ED, LATIN SMALL LETTER I WITH ACUTE) for lowercase usage.

Uses and pronunciation vary by language. It appears in many languages that employ the Latin script, including Hungarian (where Í marks a long i vowel), Icelandic, Spanish, and Portuguese (where the acute accent indicates stress or a closed front vowel). In Spanish and Portuguese orthography, the accent on the vowel signals stress placement and can alter meaning in minimal pairs. In Icelandic, Í is treated as a distinct letter within the alphabet and has its own phonological value.

Typography and computer processing treat Í like other accented Latin letters: it is a single code point, distinct from I and i, and it affects sorting, collation, and text normalization differently from unaccented vowels. The character is widely supported across fonts and input methods, reflecting its common use in multiple languages that require diacritical marks for correct spelling.
