Hangul syllable Byub

In a Korean input method, type ㅂ, then ㅠ, then ㅂ. The IME treats them as the syllable's opening consonant, vowel, and closing consonant, then assembles them into one block.

As you type, the IME may update the in-progress block when it recognizes the final consonant. That is normal composition, not three separate letters left in the text.

What does 븁 mean?

By itself, 븁 is Korean text: one syllable block. Hangul is the Korean writing system, with consonant and vowel letters arranged into blocks for spoken syllables. This syllable's meaning comes from the Korean word or phrase around it; in a message, use that context to read it.

Hangul was created under King Sejong in 1443 and was first called Hunminjeongeum; a book explaining it was published in 1446. Before Hangul, Korean was written with Chinese characters and Korean methods adapted from them, such as Idu, Gugyeol, and Hyangchal, which were difficult for many people to learn. Printed books helped Hangul spread across social classes. It became Korea's official writing system in 1894. Japanese rule began in 1910, and Hangul lost that official status; Korean scholars continued studying and using it.

The block is formed from an opening ㅂ, the vowel ㅠ, and a closing ㅂ. Unicode can represent a Hangul syllable as one character or as a sequence of joining letters. Fonts arrange those parts inside a square cell, so their shape and spacing can vary while the character stays the same.
