Hangul syllable hwess

휐 is one Hangul syllable block, not a fixed message.

Jamo are the individual Korean letters that combine into a syllable block. Unicode builds the label “hwess” from the short names of 휐’s components; it identifies the encoded parts, not a translation or a Korean word definition.

Hangul’s history is not this block’s origin. Its first record, under the name 훈민정음 (“Correct Sounds for Instructing the People”), is dated 1443; an explanatory book appeared in 1446. The book described the new letters and how they build syllables. Hangul was designed for Korean speech, while hanja (Chinese characters used in Korean writing) continued alongside it. After the Gabo Reform of 1894, the script was commonly called 국문 or 국서; 한글 was widely used as its name by 1928. These dates belong to the script, not 휐.

Why does 휐 change shape?

The font draws the outline; the character identity stays the same.

휐 canonically decomposes to 휐: an initial jamo, a vowel jamo, and a final jamo. NFC can compose that sequence into 휐; NFD can split it back into its parts. The font supplies the strokes, so the same character may look different across fonts.
