The fonts are included, but as Type 3, as Bruno said.

Nothing to do with encodings; just with how the glyphs themselves are

The figures are imported as .ps pages, created in Textures !
(They were not exported as .eps , which is doubtless the reason that
these images cause problems in some viewers.)
But the whole file was done using TeX + dvips .
Type 1 versions of the fonts must have been available to the authors,
but they have neglected to use them.

Now in Acrobat Reader, or Adobe Reader, go to a page where there
are missing images. Change the magnification.
What I then see is part of the missing bits flash up momentarily,
before the page image stabilises.
It's as if there are several layers, each the size of the whole page,
which are opaque rather than transparent. Thus a later layer obscures
an earlier one, so that only the text towards the end of the 2nd column
However, I don't think there is any explicit filling of a page-sized
(The .ps file views file, with all the figures, using Ghostview under
but distilling using Acrobat Pro doesn't help.)
Rather I suspect that the imported images reset the PostScript
causing earlier material on the page to be discarded.
This would be due to importing a .ps (rather than .eps ) file for a
where there is a complicated header section that uses PostScript
operators that are forbidden for EPS files.
Textures' header is very complicated, and I've not yet located where
the trouble is triggered, or whether there's an easy way to fix the
