About the fullwidth left square bracket symbol

In East Asian text processing and typesetting, the fullwidth left square bracket appears in CJK (Chinese, Japanese, and Korean) documents where characters occupy a uniform square space. It serves as the opening bracket in paired punctuation, mirroring the width of adjacent ideographs for visual alignment. This character is part of the Halfwidth and Fullwidth Forms block, designed to match the typographic conventions of monospaced East Asian writing systems.
