U+00D3 "Ó" Latin Capital Letter O with Acute Unicode Character
Unicode Version 17.0
Ó
U+00D3 "Ó" Latin Capital Letter O with Acute is a precomposed character in the Latin script that represents the letter O modified by an acute accent mark, indicating a specific pronunciation such as a rising or stressed tone in languages like Spanish, Irish, and Portuguese. It is encoded as a single code point in Unicode to ensure compatibility with legacy systems and to simplify text processing, though it can also be represented as a sequence of a base O (U+004F) followed by the combining acute accent (U+0301). This character is commonly used in words like "Ópera" in Portuguese and "Óleo" in Spanish, and it is distinct from the uppercase O with acute found in other scripts, such as the Cyrillic.
