Left Square Bracket Extension Symbol

There is no legacy Windows Alt code for Left Square Bracket Extension because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+23A2, which you can use as ⎢ in HTML, \23A2 in CSS, or type with Alt+9122 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Left Square Bracket Extension is outside both legacy code pages, which is why U+23A2 is the identifier that works across Word, HTML, CSS, Python and JavaScript. Left Square Bracket Extension has no named HTML entity, so use the numeric escape ⎢ or the hex escape ⎢.
