U0049

U0049 refers to the Unicode code point U+0049, which represents the Latin capital letter I. It is part of the Basic Latin block and has the official Unicode name LATIN CAPITAL LETTER I. The decimal value of the code point is 73. In UTF-8 it is encoded as 0x49, and in UTF-16 as 0x0049. The character’s general category is Lu (Letter, uppercase), and its bidirectional class is L, indicating left-to-right text processing.

The letter I is used across languages that employ the Latin script, serving as a vowel in many languages and as a consonant in others depending on context. Its uppercase form U+0049 has the lowercase counterpart U+0069 (LATIN SMALL LETTER I). As part of standard encoding practices, U+0049 participates in case mapping and normalization rules defined by the Unicode standard.

In computing, U+0049 commonly appears in plain text, programming identifiers, and data interchange where ASCII-compatible characters are required. Because it is the same as the ASCII capital I, it aligns with the ASCII encoding for the uppercase letter I in systems that support Unicode.
