Package: xpdf
Version: 3.03-7

I seem to be having the same problem with some text not showing up in
some pdf files.  I've also been able to debug the problem and possibly
track down the cause.

It seems to be the different behaviour between xpdf and poppler with
external font substitution in the SplashOutputDev::doUpdateFont method.

In the example file
(http://ww1.microchip.com/downloads/en/DeviceDoc/21984e.pdf) the
external ttf font ArialMT is substituted for a local pfb font Helvetica
(/usr/share/fonts/type1/gsfonts/n019003l.pfb).

In the poppler version of the code the font file n019003l.pfb is loaded
as a TrueTypeFont as defined in the pdf file.  In the xpdf version the
font file's type is detected by lower level code and this type is then
used to load the font.
