U+5BBB "宻" CJK Unified Ideograph-# Unicode Character

U+5BBB "宻" CJK Unified Ideograph-# is a Chinese character that functions as a variant of the more common character "密" meaning dense, secret, or close, and it is used in East Asian languages such as Chinese, Japanese, and Korean. Structurally, it combines the radical "宀" representing a roof or covering with the phonetic component "宓," which together convey the notion of something being tightly packed or concealed. In historical texts, "宻" appears in classical literature and calligraphy as an interchangeable form, though in modern usage it is less frequent than its standard counterpart.
