U+038F "Ώ" Greek Capital Letter Omega with Tonos Unicode Character

U+038F "Ώ" Greek Capital Letter Omega with Tonos is an uppercase letter in the Greek script used to represent the long vowel sound of omega with a stress accent, known as a tonos, which indicates primary stress in modern Greek polytonic orthography. This character is typically employed in writing Greek words where the omega syllable carries emphasis, such as in the word for "handwriting" or "signature" (υπογραφή). It appears in the Greek and Coptic block of Unicode and is distinct from its lowercase counterpart, ώ (U+03CE), which represents the stressed omega in lowercase. This letter is essential for accurate representation of Greek text, particularly in historical, linguistic, or academic contexts that require precise diacritical marking.
