Yeah, we can do, instead:

0x2013 => '--', # EN DASH
0x2014 => '---', # EM DASH

I was actually in doubt about those ;-)

Btw, when producing HTML documentation, Sphinx should convert:
-- into EN DASH
and:
--- into EM DASH

So, the resulting html will be identical.

No, I suspect that the line size won't be an issue. Some care should
taken when EN DASH and EM DASH are used inside tables.
