U+FE43 "﹃" Presentation Form for Vertical Left White Corner Bracket Unicode Character

U+FE43 "﹃" Presentation Form for Vertical Left White Corner Bracket is a typographic variant specifically designed for use in vertical text layouts, such as traditional Chinese or Japanese writing. It represents the left side of a white corner bracket shaped like a small, open square corner, and is intended to replace the standard left corner bracket (U+300C) when text is arranged in vertical columns rather than horizontally. This character ensures proper orientation and visual consistency within specialized typesetting systems, supporting legacy encoding standards like Chinese national standard (CNS) character sets and the Unicode CJK Compatibility Ideographs block.
