U+FE3B "︻" Presentation Form for Vertical Left Black Lenticular Bracket Unicode Character

U+FE3B "︻" Presentation Form for Vertical Left Black Lenticular Bracket is a typographic glyph used primarily in East Asian scripts, specifically designed to serve as the left half of a black lenticular bracket when text is arranged in a vertical writing direction. Unlike its standard horizontal counterpart, this presentation form is part of the CJK Compatibility block and is intended to harmonize with vertical text lines, maintaining the bracket's visual structure as a rounded, parenthesis-like shape that opens to the right. It is most commonly employed in traditional Chinese, Japanese, and Korean documents, such as in book titles or official forms, to denote enclosed content without disrupting the flow of vertical composition.
