We write Hangul in units of syllables. Although Hangul collapsing is very suitable for writing Korean, it is very difficult to transcribe the pronunciation of a foreign language such as English or a foreign language with a different syllable structure from Korean in Hangul. In order to develop Hangul into the world's script, the Hangul Community Font Research Association has developed a Hangul writing font (Hangeul Community Font 5.0) and is distributing it for free. We would like to distribute mobile input devices for writing Hangul for free.
