What 챟 means
It combines the initial consonant ㅊ, vowel ㅐ, and final consonant ㅎ into one syllable block. Unicode’s NFD form can store the same syllable as separate jamo (component letters); Unicode treats that sequence as canonically equivalent to 챟.
The history belongs to Hangul as a script: it was created in 1443, and the explanatory work Hunminjeongeum was completed in 1446 to fit Korean sounds and widen access to writing.

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.
