list of Unicode characters

I have MPro version 7.08 (2015-feb-16), and it's tiresome to deal with 
the likes of   –   or   é   (which translate to N-dash and e-acute) 
when people email an article for a magazine.  See attached little 
screenshot of a test email exported as textfile from MPro.

Do recent versions of MPro do a better job of saving-as-text when the
file contains Unicode characters like these?

If yes, which MPro version do I need to get?

If no, does there exist a definitive list of these puzzling strings of 
strange characters?  Where can I obtain it?  I could use the list to
write my own Convtext script to handle them.  At the moment my script
is piecemeal, from adding characters as and when they turn up.
