History & usage: The character depicts MATHEMATICAL LEFT WHITE TORTOISE SHELL BRACKET. In the name, the tokens LEFT and BRACKET signal position and function as a bracket marker in formulas and structures; WHITE describes a color qualifier that affects contrast rather than form; TORTOISE SHELL is a shape/qualifier label used to distinguish a specific curved contour from other brackets. In orthography and typography, such shape and qualifier tokens guide how punctuation or delimiter marks are designed, spaced, and related to surrounding glyphs, while leftward or rightward orientation informs alignment in mathematical notation. 2–3 practical usage contexts follow. In scholarly dictionaries and grammars, editors cite this glyph as a distinct delimiter with a unique typographic shape to preserve meaning in complex equations. In educational primers and classroom materials, it helps students learn how variable-sized brackets group terms across line breaks and display modes. In archival transcription and paleography, scholars note its left-leaning form and its role in delimiting nested expressions for precise reading. Cross-platform appearance and accessibility remain important for all users of mathematical notation.
