A leader in typography is a series of characters, usually dots or dashes, that are used as a visual aid to connect items on a page that might be separated by considerable horizontal distance. For example, dot leaders are often used in tables of contents to connect section headings with the page numbers on which those sections begin.
Although manual dot leaders are most often represented as a series of full stop characters, there are at least three Unicode characters dedicated to the representation of dot leaders. These are U+2024 ONE DOT LEADER (․), U+2025 TWO DOT LEADER (‥), and U+2026 HORIZONTAL ELLIPSIS (…), a three dot leader.
