What 󠆨 means
They preserve a character's written form without adding another character. A Unicode proposal from 2000 describes an invisible selector after a base character as a way to request a variant form. Later, the Ideographic Variation Database (IVD) allowed different communities to register the sets of forms they need. In Japan, fine differences in kanji—the Chinese-derived characters used in Japanese—such as 葛 and 辻 can matter in personal names, place names, and official records.
