Unicode Version 17.0
界
U+754C "界" CJK Unified Ideograph-# is a foundational character in written Chinese, Japanese, and Korean, commonly used to mean "world," "boundary," or "realm." Its structure combines the semantic radical 田 (field or area) with the phonetic component 介, visually suggesting a defined expanse or limit. In Chinese, it appears in words like 世界 (shìjiè, "world") and 边界 (biānjiè, "border"); in Japanese, it is read as kai or kyō and used in terms such as 世界 (sekai) and 界隈 (kaiwai, "neighborhood"). The character also carries philosophical weight in various contexts, representing the conceptual boundaries of knowledge or existence.
