U+3090 "ゐ" Hiragana Letter Wi Unicode Character

U+3090 "ゐ" Hiragana Letter Wi is a historical hiragana character that was once part of standard Japanese orthography, representing the phonetic syllable "wi" pronounced similarly to the modern "i" or "ui." It was commonly used in classical Japanese texts and during the Heian period before disappearing from everyday use following the major script reforms after World War II. Today, it appears primarily in historical documents, traditional poetry, and some proper names, and it remains a point of study for linguists and those learning older forms of written Japanese.
