Hangul Syllable Weot

By itself, 웥 is a syllable block, not a complete message.

Hangul groups its letters, called jamo, into written syllable blocks. 웥 consists of initial ㅇ, vowel ㅝ, and final ㅌ. A lone block has no fixed message; if someone sends it alone, ask what they mean.

is 웥 an emoji or a Korean character?

It is a Hangul text character, not an emoji.

Unicode derives Hangul syllable names from their component letters, so the name labels the parts rather than translating the syllable into Korean.

King Sejong's Hangul project dates to 1443. It offered a way to write Korean without adapting Chinese characters through methods such as Idu, Gugyeol, and Hyangchal. The 1446 Hunminjeongeum, a book explaining the new script, described its purpose and principles. Hangul is the usual name in South Korea; Choseongul is preferred in North Korea.

how do I type 웥 on a Korean keyboard?

Use Korean input and enter initial, vowel, then final.

On the standard 2-set (Dubeolsik) layout, type dnjx: d gives ㅇ, n + j builds ㅝ, and x gives ㅌ. The Korean IME joins them into one block.

If you see 웥 or separate jamo, that is the decomposed form. Unicode normalization can convert between it and the precomposed block; NFC recomposes the jamo when one block is needed.
