U+002C "," Comma Unicode Character

U+002C "," Comma is a fundamental punctuation mark used across countless writing systems to indicate a brief pause between elements within a sentence, such as items in a list, clauses, or coordinate adjectives. It also serves critical functions in numerical notation, like separating the integer and fractional parts of a number in many cultures, and in technical contexts, such as delimiting function arguments in programming languages. As both a ubiquitous text element and a foundational unit in computer data formatting, the comma is essential for clarity, structure, and parsing in both human and machine communication.
