Subscript Zero Symbol

There is no legacy Windows Alt code for Subscript Zero because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+2080, which you can use as ₀ in HTML, \2080 in CSS, or type with Alt+8320 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Subscript Zero is outside both legacy code pages, which is why U+2080 is the identifier that works across Word, HTML, CSS, Python and JavaScript. Subscript Zero has no named HTML entity, so use the numeric escape ₀ or the hex escape ₀.
