Double Prime Symbol

There is no legacy Windows Alt code for Double Prime because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+2033, which you can use as ″ in HTML, \2033 in CSS, or type with Alt+8243 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Double Prime is outside both legacy code pages, which is why U+2033 is the identifier that works across Word, HTML, CSS, Python and JavaScript. HTML also defines the named entity ″ for Double Prime, but the numeric form ″ is safer when compatibility is uncertain.
