The encoding files are in the poppler-data package, not the poppler
package.  Likely your users need to install poppler-data.

On Mac and Linux the path is hardcoded at compilation time.  It's
generally in /usr/share/poppler on Linux.  Not sure what the standard is
on Mac.  On Windows it looks in \share\poppler relative to the
installation directory.
