Greek Capital Letter Omicron Symbol

There is no legacy Windows Alt code for Greek Capital Letter Omicron because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+039F, which you can use as Ο in HTML, \039F in CSS, or type with Alt+927 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Greek Capital Letter Omicron is outside both legacy code pages, which is why U+039F is the identifier that works across Word, HTML, CSS, Python and JavaScript. HTML also defines the named entity Ο for Greek Capital Letter Omicron, but the numeric form Ο is safer when compatibility is uncertain.
