[issue30680] textwrap should treat Unicode em-dash like ASCII em-dash

[R. David Murray]

R. David Murray added the comment:

This seems sensible to me (I haven't looked at the PR, I'm talking about adding the support).  When textwrap was written python was pretty ascii oriented, so it is not too much of a surprise that unicode em dashes were not supported.
