I'm guessing that the attached PDF file must have been scanned from a hard copy without the use of OCR software, and the resulting image converted to PDF.
The output of pdffonts Anyons_Wilczek_1982.pdf (I modified the filename when I saved it) is empty - see attachment. According to http://en.wikipedia.org/wiki/PDF the PDF file format was created in 1993, and PDF version 1.3 was created in 1999. The output of pdfinfo Anyons_Wilczek_1982.pdf is: Producer: g42pdf.pl 1.0 Tagged: no Pages: 3 Encrypted: no Page size: 612 x 792 pts (letter) File size: 464443 bytes Optimized: no PDF version: 1.3 ** Attachment added: "fonts.txt" http://launchpadlibrarian.net/37324415/fonts.txt -- Bad rendering of certain pdf files https://bugs.launchpad.net/bugs/490918 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
