What 찶 means
찶 is one syllable block in the Korean writing system. Hangul is the Korean alphabet: its letters, called jamo, combine into blocks representing syllables. 찶 combines initial consonant ㅊ, vowel ㅏ, and final consonant cluster ㄿ; “calp” is Unicode’s construction label for that combination, not a Korean word or translation.
Hangul was completed in 1443, and the guide Hunminjeongeum explained its design in 1446. It was created to make written Korean speech more accessible than using Chinese characters. Fonts can vary the stroke details of 찶 without changing its character identity.

1Why does 찶 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
