Today I finished a book in *.rtf format and saved it as *.epub also.
When I inspected the file in Sigil 0.9.10 (my default epub-reader) I saw that one of four fonts wasn't embedded...
So I did it by hand - and doing so, I looked out for the reason; May it be possible that AW do not embed fonts whose filenames are all in versal?
Also extension.
Because I noticed that this font shows up in AW as all others installed fonts; but in the 'exclude-fonts'-option for epub-export it doesn' show at all...
Not a big thing, but I thought it may help to mention it.
