U+23E5 "⏥" Flatness Unicode Character

U+23E5 "⏥" Flatness is a typographic symbol formally designated in the Miscellaneous Technical block of the Unicode standard, where it is used to represent the concept of flatness or a planar surface in technical diagrams, engineering drawings, and geometric dimensioning and tolerancing (GD&T) annotations. Its visual design typically resembles a small, solid, horizontally oriented trapezoid or a truncated triangle, a form that conveys a level, even, or non-curved state. While not a common character in everyday text, it serves a precise role in standardized technical communication, allowing engineers and drafters to indicate that a surface must meet specific flatness tolerances without resorting to lengthy descriptive notes.
