What 댇 means
Use Korean input and type ㄷ, ㅐ, then final ㄷ.
On Dubeolsik, the Korean keyboard layout, those keystrokes are e-o-e: e enters ㄷ, o enters ㅐ, and the last e enters ㄷ in final position. A Korean input method joins them into one syllable block. If the letters stay separate, switch the input method to Korean and use a text field that composes Hangul.
What does 댇 mean by itself?
It is a Korean syllable block, not a fixed message by itself.
Read 댇 as part of the Korean word or sentence around it; an isolated block has no settled reaction meaning.
Hangul was created in 1443 so Korean could be written with letters representing speech sounds. Hunminjeongeum, the text that introduced Hangul, was completed in 1446. Modern Korean spelling follows the unified proposal from 1933.
A Korean writing unit: use it in Korean text or a discussion of Hangul, not as a stand-alone reaction.
A bare 댇 is not a standard emoji reaction; it is a syllable block.

1Why does 댇 look different in different fonts?
It can. Fonts draw the jamo inside the square syllable cell with slightly different shapes or placement. That changes the drawing, not the underlying character.
