What 잭 means
It is Korean spelling, not an emoji. 잭 spells the sound “jaek” and gets its sense from the surrounding word, often a transliteration of English Jack.
Hangul builds syllable blocks from smaller letters to record Korean speech, so this character is spelling rather than a picture. Fonts may draw its strokes differently, and software may store the matching smaller letters underneath, but the character and sound stay the same.
Neutral spelling in Korean writing; the nearby words supply the meaning.
Do not treat it as a picture emoji.

1Why does 잭 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.
