U+1FCB "Ή" Greek Capital Letter Eta with Oxia Unicode Character
U+1FCB "Ή" Greek Capital Letter Eta with Oxia is a precomposed glyph that represents the uppercase Greek letter Eta (Η) combined with the oxia, an acute accent mark historically derived from the ancient Greek pitch accent and used in modern polytonic orthography to indicate a stressed syllable in words like "ἥλιος" (sun). This character is part of the Greek Extended block and is primarily employed in scholarly texts, liturgical writings, or other contexts where traditional Greek diacritics are preserved for linguistic or historical accuracy. It is distinct from the separate combination of a capital Eta followed by a combining acute accent, as it exists as a single encoded unit for legacy compatibility and ease of use in older character sets.
