U+0027 "'" Apostrophe Unicode Character

Unicode Version 17.0

'

U+0027 "'" Apostrophe is a versatile punctuation mark that originated from the typewriter's single quote key and is formally classified as a punctuation, connector in the Unicode standard. It serves as both a contraction marker in words like "don't" and a possessive indicator in terms like "John's", though its use has become more complex in the digital age due to its common and often problematic substitution for the curly or typographic apostrophe (U+2019) and the single opening or closing quotation mark. In computer programming and markup languages, it frequently delimits string literals and can cause syntax errors if not properly escaped, making it a critical character for both human language and machine-readable code.
