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.

Thanks,
