U+0022 " Quotation Mark Unicode Character

U+0022 " Quotation Mark is a fundamental typographic symbol used to denote the beginning and end of a direct quotation or a piece of spoken dialogue in written text. It is identical to the standard double quote key found on most keyboards and is widely employed in programming languages to delineate string literals. In digital contexts, it is distinct from typographic or curly quotes, as it lacks directional asymmetry and is often called a "straight" or "dumb" quote. The character traces its origins back to ancient Greek and Latin manuscripts, where it was used as a marginal annotation, though its modern purpose as a paired punctuation mark became fully standardized in the printing press era and later formalized in the Unicode standard for universal encoding.
