Unicode 18.0.0

How is an em dash different from a hyphen?

A punctuation dash distinct from the ASCII hyphen. Code points: U+2014. Some constrained formats, code syntaxes and fonts do not expect it. A non-equivalent fallback is "--" (ASCII approximation). Two hyphens, not the same character. Exact string match: no. NFC match: no. Appearance and meaning were not tested. Font coverage, shaping, and application acceptance were not tested, so those results are unknown.
