Corner brackets (「」) wrap dialogue or quotations; double corner brackets (『』) wrap larger units like book titles or periodicals. Where Western text reaches for quotation marks or italics, the vertical-writing tradition used angular, directional bracket shapes instead. Even now that horizontal writing is standard, publishing and official documents still often favor corner brackets over quotation marks.
The interpunct (·, U+00B7 or the punctuation-specific U+318D) lists items in a parallel relationship — "국어·영어·수학" (Korean·English·Math) reads as a tighter, more equal grouping than a comma would. Date notation (2024. 3. 1.) also conventionally follows each number with a period.
The formally correct ellipsis is technically six raised dots (⋯⋯), though in practice it's commonly replaced with an ordinary ellipsis (…… or ...). Worth knowing: the tilde used for ranges ("10~20개") has two different Unicode code points — wave dash (U+301C) and fullwidth tilde (U+FF5E) — which can render differently depending on font and OS.
When to use
Follow corner-bracket and interpunct conventions for publishing, official documents, or a traditional feel. Ordinary quotation marks and commas are often sufficient for general web UI.
