U+31D9 "㇙" CJK Stroke St Unicode Character

Unicode Version 17.0

U+31D9 "㇙" CJK Stroke St is a specific glyph representing a standardized stroke type used in the writing system of Chinese characters, known as the "Stroke St" or "Straight Stroke," which is integral to the Unicode CJK Strokes block for encoding the individual building blocks of Chinese, Japanese, and Korean (CJK) logographs. This character corresponds to the elongated, unbent line segment frequently employed as a component in complex character shapes, often appearing as a vertical or horizontal stroke in calligraphy and typography. Its inclusion in Unicode allows for precise decomposition and analysis of CJK characters in digital text processing, handwriting recognition, and linguistic studies, ensuring that the fundamental structure of East Asian scripts is preserved in electronic form.
