What 삫 means
It writes a Korean syllable.
Hangul was devised in 1443 and explained in 1446 in Hunminjeongeum, a guide to the new script. It offered Korean speakers a learnable way to write their language alongside Chinese-character-based writing.
How do I type or render 삫?
A Korean input method and Hangul font handle it.
The keyboard assembles the block; a Hangul-capable font and shaping support display it. Unicode can also encode Hangul syllables as Jamo sequences—the letters used to build blocks. A square or broken mark signals a rendering problem.
