Meaning & usage

Double vertical (║) forms part of a text-based line, frame or shaded block.

Match neighboring pieces and use a monospace font when alignment matters; proportional fonts can break a carefully arranged box.

The double vertical piece uses parallel double strokes. Match that style with adjacent box pieces; U+2551 is the exact code to preserve its geometry.

double vertical occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with ║ in search, filenames or text processing.

How to type double vertical

Windows
Use Win + . for the emoji and symbol panel, or Character Map for supported fonts. In Microsoft Word, enter each hexadecimal code (2551) and press Alt + X. There is no universal decimal Alt code for this character; legacy Alt codes depend on the code page.
Mac
Open Character Viewer with Control + Command + Space and search for double vertical. With the Unicode Hex Input keyboard enabled, hold Option and enter the UTF-16 units shown above. Standard Option shortcuts do not cover every Unicode symbol.
Linux
In compatible GTK applications, press Ctrl + Shift + U, enter 2551, then Enter. Enter each code point separately for sequences. Other desktops or apps may require their character picker.
iPhone & Android
Look for double vertical in your emoji keyboard if available, or copy it here and paste. Save frequently used symbols as a text replacement or keyboard shortcut; availability varies by keyboard.
