Top Square Bracket Symbol

There is no legacy Windows Alt code for Top Square Bracket because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+23B4, which you can use as ⎴ in HTML, \23B4 in CSS, or type with Alt+9140 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Top Square Bracket is outside both legacy code pages, which is why U+23B4 is the identifier that works across Word, HTML, CSS, Python and JavaScript. Top Square Bracket has no named HTML entity, so use the numeric escape ⎴ or the hex escape ⎴.
