Hangul Syllable Muss

뭈 is a syllable block in Hangul, the Korean writing system, made from letters ㅁ, ㅜ and ㅆ; alone, it has no fixed message. Hangul, recorded as Hunminjeongeum in 1443, was explained in a 1446 book as an easier way to write Korean than using Chinese characters. Korean input methods join individual letters, called jamo, into blocks; the same text can also be stored as separate letters and look identical.
