What 󠆆 means
Only a registered base-selector pair can request a specific glyph form.
Variation sequences preserve glyph distinctions in plain text without encoding every form separately. Han characters are Chinese-origin characters used in Chinese, Japanese, and Korean writing. Adobe-Japan1, the first IVD collection, registered 2007-12-14 for Japanese font variants. Moji_Joho, registered 2014-05-16, records forms needed in Japanese government administration.
Only a registered pair requests a form. An unregistered or unsupported pair leaves the base character unchanged; the selector stays invisible.
