I am trying to thumbnail all of the pages in a PDF using ImageMagick. Some process fine, but some of the PDFs fail midway through.
Here is the log:
convert sample.pdf -resize 190 test.jpg

I tried googling about errors in reading the font stream, but I could not find useful information.
Is this caused by lack of fonts in the system?
I tried pdffonts on the pdf and got many
Error: Illegal entry in bfchar block in ToUnicode CMap
all over the place.
This may be a point, the PDFs are in Japanese.
