Any text typeset in the ZapfDingbats font is shown wrongly in poppler-based viewers, e.g., xpdf. This boils down to <alias binding="same"> <family>Zapf Dingbats</family> <accept><family>Dingbats</family></accept> </alias> instead of <alias binding="same"> <family>ZapfDingbats</family> <accept><family>Dingbats</family></accept> </alias> (notice the space between "Zapf" and "Dingbats" in the original file).
Fixed long ago. Try -r1, it just went stable. *** This bug has been marked as a duplicate of bug 303591 ***
