There is cleanly no major bug in our code; with 50k+ downloads per
month and users everywhere, we would have heard about it before, and
our code just embeds the TTF information; it doesn't do any drawing of

Adobe's preflight tool in Windows is telling us there is something
wrong with those specific glyphs, when embedded in our PDFs.  We don't
know at the moment whether
(a) we are missing out some optional info or flag when we embed the
font file, or
(b) there is a bug in those glyphs in that font which surfaces under
some rare situations.

We will keep investigating for a while, anyway.
