Uppercase Letter
Info · Characters
Uppercase letters represent the capital forms of alphabetic characters in a given script. These are typically used at the start of sentences, for proper names, and in cases where emphasis or typographic distinction is required. In Unicode, the 'Lu' category encompasses all uppercase alphabetic characters from various world scripts, including Latin (A, B, C), Greek (Α, Β, Γ), Cyrillic (А, Б, В), and many others. They are distinct from lowercase and titlecase forms, and their Unicode properties allow for case-sensitive processing in applications.
