U+7637 "瘷" CJK Unified Ideograph-# Unicode Character

U+7637 "瘷" CJK Unified Ideograph-# is a rare and complex Chinese character that falls under the radical for illness, represented by the component 疒. Its standard reading in Mandarin Chinese is "sè" or "cè," and it is defined in classical dictionaries as referring to a specific type of ailment or discomfort, often associated with chills or a feeling of coldness in the body, akin to the sensation of a fever or ague. This character is not commonly used in modern Chinese texts but appears in historical or highly specialized medical contexts, particularly in older medical manuscripts where it described symptoms similar to malaria or intermittent fevers. As a CJK unified ideograph, it is encoded for compatibility with East Asian scripts, though its practical usage remains extremely limited.
