Hangul syllable Hoec

It is one Hangul syllable, not a symbol with a fixed meaning.

The canonical decomposition of 횣 uses three conjoining jamo: an initial consonant, a vowel, and a final consonant. Jamo are the letters that form Hangul syllables. The familiar standalone forms ㅎ, ㅚ, and ㅊ are related compatibility jamo, but they are not the exact characters in that decomposition. A Korean word supplies the lexical meaning.

Why does Hangul use syllable blocks?

Each block groups the letters of one Korean syllable.

Hangul was created in 1443 to make Korean writing more direct. The Hunminjeongeum, a guide to the new script, appeared in 1446.

Before Hangul, Korean writers adapted Chinese characters, called Hanja in Korean, in systems such as Idu, Hyangchal, and Gugyeol. Hangul spread through personal, religious, educational, and practical writing while official documents remained mainly in Chinese characters. It became the national writing system in 1894 and was standardized later.

How do I type or store 횣?

A Korean input method composes the block from jamo.

Fonts can change the placement and proportions of the components inside the block. That is a font difference, not a different text character.
