Is that the way fontspec is doing it? If so, what is the benefit of
embedding the same font multiple times in the PDF? If there is no
benefit, would this be a bug in fontspec? Because normal end users
should not have to know (or simply do not know) the background effect of
using newfontface or fontspec.
