Hangul stands apart from every other major writing system as a script deliberately invented by a single person with explicit design principles. Its 11,172 syllable blocks, each composed from an initial consonant, a medial vowel, and an optional final consonant, make it both scientifically systematic and visually distinctive. The jamo blocks encode these individual components, enabling both precomposed syllable rendering and decomposed linguistic analysis.

King Sejong the Great promulgated Hangul in 1443 through the Hunminjeongeum, a document whose preface declared the script was created so that common people could easily learn to read and write. Each consonant letter was designed to depict the shape of the speech organ used to produce it — a revolutionary featural principle found in no other widely used script. Despite fierce opposition from the scholarly elite who favored Chinese characters, Hangul gradually gained acceptance. The script was banned during Japanese colonial rule (1910–1945), and its survival became a point of fierce national pride. Unicode encodes the full set of 11,172 modern Hangul syllables in a contiguous block, plus jamo components in separate blocks for flexibility.
