What 벛 means
By itself, 벛 is one Hangul syllable block. Its jamo (letters) are ㅂ, ㅓ and ㅊ: initial consonant, vowel and final consonant. “Beoc” is Unicode’s Latin label, not a Korean word.
King Sejong's court devised Hangul in 1443. The 1446 Hunminjeongeum guide explained its new letters for writing Korean directly instead of relying on Chinese characters. That's the script's history, not a special origin for 벛.
Fonts may arrange its strokes differently. Unicode also has a separate-jamo form of the same syllable, which software may join.
