What 뫌 means
It is a Korean Hangul syllable block.
Hangul joins consonant and vowel letters, called jamo, into syllable blocks; Unicode decomposes 뫌 as ᄆ + ᅪ + ᆯ.
Korean verb endings -아 or -어 can contract with -를, the object marker; an orthography article lists 뫌 in this pattern.

1Why does 뫌 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.
