U+765B "癛" CJK Unified Ideograph-# Unicode Character

U+765B "癛" CJK Unified Ideograph-# is a rare Chinese character used in classical or historical texts, primarily representing the concept of a "cold" or "chill" disease, often associated with a miasma or an epidemic illness in ancient medical terminology. It belongs to the radical for sickness or disease and appears in specialized lexicons or literary works rather than modern standard Chinese, where its usage is largely obscure. The character is encoded in the CJK Unified Ideographs block of Unicode, reflecting its role in preserving a small piece of East Asian logographic heritage, though it remains infrequently utilized in contemporary contexts.
