U+FE39 "︹" Presentation Form for Vertical Left Tortoise Shell Bracket Unicode Character

Unicode Version 17.0

U+FE39 "︹" Presentation Form for Vertical Left Tortoise Shell Bracket is a typographic glyph used in East Asian vertical text layouts, specifically serving as the opening bracket of a paired punctuation set known as tortoise shell brackets. Unlike standard horizontal forms, this character is designed to be rotated and correctly aligned within vertical writing systems, where lines of text run from top to bottom. It is classified as a vertical presentation form, a compatibility variant intended for use in contexts where explicit control over directionality is necessary, such as in traditional Chinese, Japanese, or Korean printing. The character itself resembles a tall, curved bracket opening to the right, helping to enclose supplementary or parenthetical content within a vertical column of text.
