What 챇 means
It is a Korean syllable with three Hangul parts.
Its encoded Hangul parts are ᄎ (initial consonant), ᅢ (vowel), and ᆪ (final consonant cluster). Inside a word, neighboring syllables establish how this syllable functions.
Before Hangul, Korean writing used Chinese characters and methods such as hyangchal and idu, which adapted Chinese characters to write Korean. Hangul's development culminated in 1443, and it was published with an explanation in 1446. The script was designed to represent Korean speech and make writing easier; 챇 follows its design of arranging letters into syllable blocks.
Why can 챇 look different across fonts?
Different Hangul fonts draw the same character in different styles.
The font changes the block's letterforms; that visual variation does not change the underlying Hangul character.
Neutral as part of Korean writing; its tone depends on the surrounding text.

1Why does 챇 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.
