proposal: 'dev.capabilities()' can also query Unicode capabilities of current graphics device

I agree in principle that this would be useful new feature for
dev.capabilities()

However, pdf()   *does*  support  Unicode.

The problem is that some pdf *viewers*,
notably `evince` on Fedora Linux, for several years now,
do *not* show *some* of the UTF-8 glyphs because they do not use
the correct fonts {which *are* on the machine; good old `xpdf`
does in that case show the glyphs}.
