              This took way to long to finally figure out. After chasing many ghosts it turns out that the font widths defined by the fonts are incomplete or incorrect. The font contains almost 3500 glyphs and defines only 3 width one of which is zero. The PDF contains no width information in the font dictionary either. I've tried a few other editors and they tend to crash when trying to load the font which gives further validity to the fact that font maybe corrupt.

              I've added some code to test the length of the widths vs the number of glyphs in the hopes of adding a little fuzzy logic to detect when the fonts width maybe incorrect.

              Finally worked through this issue, the file in question does not specify any fonts widths for the embedded CIDType2. In this particular case we should be using the the default DW all all glyph widths or at least that's the pattern I'm seeing.
