It needs Unicode experts. If we support Unicode, we should implemente UAX #14.
http://www.unicode.org/reports/tr14/tr14-45.html

But I am not sure some core developer love textwrap and Unicode enough to 
implement it.
It can be implemented in 3rd party package before adding it in stdlib.

Then, is U+2014 really important to implement even though we can not implement 
UAX#14 in foreseeable future?
It doesn't make sense to me.

[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.

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

[Jonathan Eunice]

New submission from Jonathan Eunice:

The textwrap module goes to great lengths to "do the right thing" when it finds 
the ASCII simulation of an em-dash (two or more consecutive hyphens), but it 
does nothing to recognize and similarly treat true (Unicode) 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.
