U+C678 "외" Hangul Syllable Oe Unicode Character
Unicode Version 17.0
외
U+C678 "외" Hangul Syllable Oe is a precomposed syllable in the modern Korean writing system, Hangul, representing the sound "oe" (a single vowel sound pronounced as [we] or [ø] in standard Korean). It is formed by combining the initial consonant placeholder ㅇ (ieung) with the vowel ㅚ (oe), which itself historically derives from the diphthong of ㅗ (o) and ㅣ (i). As a common syllable in Korean, "외" appears in words such as "외국" (foreign country) and "외부" (exterior), and its inclusion in Unicode facilitates the digital representation and processing of Hangul text across global computing platforms.
