Hangul syllable pyaes

Read it as one syllable block; its context supplies the message.

퍳 combines ㅍ as the opening consonant, ㅒ as the vowel, and ㅅ as the closing consonant. These Hangul building letters are called jamo. The Unicode name “pyaes” is formed from those pieces; it tells you how the block is built, not what to translate it as. In Korean, interpret the syllable as part of its surrounding word or sentence.

Records from 1443 and 1446 describe Hangul's creation and explain its purpose and how letters form syllable blocks. The script was designed to let people write Korean speech without first mastering Chinese characters. Hangul became the official national script in 1894; mass printing later brought it to a wider public.

Someone sent me 퍳—how should I read it?

Ask for the surrounding Korean text.

An isolated syllable cannot tell you the sender's tone or intended sentence. Ask which Korean word or sentence it belongs to; in a discussion of fonts or Unicode, the character itself may be the subject.

How do I type 퍳?

Use a Korean 2-set keyboard layout.

Switch to Korean input. On a Dubeolsik two-set layout, type V, Shift+O, then T; the Korean IME (input method) combines ㅍ + ㅒ + ㅅ into 퍳.

Unicode can store the syllable as one precomposed block or as its component jamo. Fonts determine the jamo's arrangement, shape, and size within the block, so its appearance can differ without changing the character.
