U+4E28 "丨" CJK Unified Ideograph-# Unicode Character

U+4E28 "丨" CJK Unified Ideograph-# is a fundamental stroke in East Asian writing systems, representing a vertical line that serves as both a standalone character and a component of many complex Chinese characters. In traditional Chinese, its literal meaning is "one" or "line," but it is most commonly used as a radical or stroke within other characters, contributing to their structure without carrying a distinct lexical definition. This character is also known as "gǔn" in Chinese, and it belongs to the Kangxi Radicals (Radical 2), where it symbolizes the concept of a straight, downward stroke. As part of the CJK Unified Ideographs block, it is encoded for use in Chinese, Japanese, and Korean scripts, where it functions primarily as a graphical element in the composition of thousands of logograms.
