U+23E4 "⏤" Straightness Unicode Character

U+23E4 "⏤" Straightness is a typographic symbol classified under the Miscellaneous Technical block, designed to represent the concept of straightness, often used in engineering, drafting, or geometric notation to indicate that a line or surface must be perfectly straight without deviation. Its appearance is a simple, solid horizontal bar, distinguishing it from similar dashes or hyphens by its specific technical purpose rather than grammatical or punctuation use. This character serves as a concise visual cue in technical drawings or diagrams, where it communicates a precise requirement for alignment or linearity, and it is encoded separately to avoid ambiguity with standard ASCII characters like the hyphen-minus or em dash.
