Unfortunately this PR has languished for a long time. Sorry for that! Linking back to the issue explicitly: https://bugs.python.org/issue30680 I'm willing to help see this PR through to completion, if there's still interest in it. I haven't looked closely yet, but:
Also going to close and reopen to retrigger CI. |

Why em-dash is special than any other Unicode special characters? |

textwrapspecifically recognizes and specially treats the ASCII simulation of an em-dash (two or more consecutive hyphens). It does nothing, however, to recognize and treat true em-dashes (aka'\N{EM DASH}','\u2014', or U+2014). Real em-dashes should get at least as good a treatment as simulated em-dashes.This PR adds parallel treatment, plus tests.
(Some tests for "degenerate" cases of the simulated em-dash, e.g. three or more consecutive hyphens, are not replicated for the true em-dash, because repeating the true em-dash has no common sensible meaning.)
