Horizontal Line Extension Symbol Meaning
⎯ (Unicode U+23AF) is named HORIZONTAL LINE EXTENSION. In practice, it’s used as a line segment in text so a horizontal rule or connector can visually continue across content. Unlike the plain hyphen “-”, this character is intended to look like an extended horizontal bar, which makes it useful for UI labels, tables, section dividers, and structured text. In technical documents and typography, it helps indicate continuation, separation, or a “line” element without needing graphics. Because it’s a dedicated Unicode glyph, it can be easier to align consistently in text-based environments.
