U0055

U0055 refers to the Unicode code point U+0055, which corresponds to the Latin capital letter U. It is part of the Basic Latin block, the same range that contains the 7-bit ASCII characters. In typical character encoding, U+0055 is identical to the ASCII code 85 and the hexadecimal value 0x55.

In Unicode, the character is categorized as a letter, with the specific general category Lu (Letter, uppercase). The script associated with this code point is Latin. Its lowercase counterpart is the Latin small letter u, encoded as U+0075, so case mapping between U and u is defined in Unicode.

Encoding details: In UTF-8, U+0055 is encoded as a single byte 0x55. In UTF-16, it is also represented with a single 16-bit unit 0x0055. Because it lies within the ASCII range, it is widely supported across programming languages, text editors, and data interchange formats that rely on ASCII-compatible encodings.

Usage: The character U is used in virtually all languages that employ the Latin alphabet, including English. It appears as the initial or a component of words, abbreviations, and identifiers. Beyond its literal use, U can appear in technical contexts such as file names, code, and data strings that utilize the Latin script.

Legacy and related code points: U+0055 sits in the contiguous ASCII-compatible range of Unicode, with nearby uppercase and lowercase forms such as U+0056 (V) and U+0075 (u). This placement reflects Unicode’s design to preserve compatibility with ASCII.
