I never have any problems with em, en etc. with my PRS-300 with the standard firmware and no extra fonts. I just make sure that my files are encoded as utf8. Non-breaking spaces can then be entered from the keyboard as <alt>255, en as <alt>0150 and em as <alt>0151. Smart quotes can also be used and many other special characters.
I also use calibre for all my conversions and have no problems with these characters. I don't use Sigil so can't comment on whether it supports utf8 files.
