U+30F0 "ヰ" Katakana Letter Wi Unicode Character

U+30F0 "ヰ" Katakana Letter Wi is a relatively rare katakana symbol historically used in Japanese to represent the syllable "wi," which is now largely obsolete in modern standard Japanese due to sound changes that merged it with the "i" sound. Its hiragana counterpart is ゐ, and it was once part of the classical kana system, primarily appearing in older texts, names, or stylized writing. In contemporary usage, ヰ may be found in historical contexts, such as in the word "whiskey" (ウイスキー) sometimes written with ヰ for a nostalgic or archaic feel, or in the place name "Iwami" (石見). Though no longer a standard character in everyday Japanese, it remains encoded in Unicode for the sake of historical and linguistic preservation.
