Rightwards Two-Headed Arrow With Tail With Double Vertical Stroke

Rightwards Two-Headed Arrow With Tail With Double Vertical Stroke is a specialized arrow variant from the Supplemental Arrows ranges, typically used in advanced mathematical notation, category theory, or detailed technical diagrams that need a more specific directional symbol than the basic arrow set provides.

Unicode block: Supplemental Arrows (U+2900–U+2BFF (A/B/C ranges)). As mathematics and diagramming needs grew beyond the original Arrows block, Unicode added several supplemental arrow ranges covering more specialized directional and relational notations.

At Unicode code point U+2918 (decimal 10520), Rightwards Two-Headed Arrow With Tail With Double Vertical Stroke is the 25th of 128 characters cataloged in this category on How To Type Any Symbol. In terms of typing methods, like most characters outside the 0–255 legacy codepage range, it has no dedicated Alt-code or single-key shortcut on Windows or Mac, so copy-paste is the standard, universal method for typing it. Regardless of platform, clicking the copy button above places the exact character on your clipboard, ready to paste into any application that accepts Unicode text.

💡 Good to know: In LaTeX and technical typesetting, most supplemental arrows have dedicated packages/commands (often from `amssymb` or similar) rather than needing direct Unicode input.
