There are missing characters. For example the \mathcal{D} and \mathsf{T} on the first page. What should be there in the optimized PDF instead? The same characters as in the original pdf. This was as far as I could easily reduce this testcase.

Thank you for the detailed bugreport. Unfortunately I could not reproduce the bug: for me Ghostscript 8.54 and Ghostscript 8.61 both produce a correct \mathcal{D} and \mathsf{T} in Bishop-thesis.psom.pdf. See the attached output of Ghostscript 8.54. * Is the attached Bishop-thesis.psom.pdf correct? * Please sync to r92 and rerun the conversion, and copy-paste its output. That one reports the Ghostscript version number (Type1CConverter: using interpreter ...). * If your Ghostscript version number is less than 8.54, please upgrade (sudo apt-get install gs-gpl) immediately. For best results, please upgrade to at least 8.61.

Thanks for investigating. 

The Bishop-thesis.psom.pdf that you attached is NOT correct.
I attach a screenshot of viewing Bishop-thesis.psom.pdf in windows adobe reader 
9.2.0
side-by-side with the viewing the original file. (The same is true if I use
sumatraPDF (SVN version r1437) or acrobat professional 7.1.0.)

I am using ghostscript 8.61 according to:
user@ubuntu804server:~/pdfsizeopt$ gs --version
8.61

Thank you for sending this detailed and specific bug report. I can confirm that the Bishop-thesis.psom.pdf is not correct. More specifically: \mathcal{D} and \mathsf{T} show up correctly when viewed in xpdf and Evince, but they are missing in Ghostscript 8.54, 8.61 and Acrobat Reader. This looks similar to the bug I tried to fix recently: the Type1C font generated by Ghostscript had a different Encoding than the original font. As a temporary fix, please run the optimization as ``pdfsizeopt.py --do-unify-fonts=false''. This prevented the bug from happening for me, see the attached files. If it doesn't help you, please attach both the original and the generated PDF, and please copy-paste pdfsizeopt's output. info: loading PDF from: Bishop-thesis.pdf info: loaded PDF of 272392 bytes info: separated to 141 objs info: found 9 Type1 fonts loaded info: writing Type1CConverter (227208 font bytes) to: pso.conv.tmp.ps info: executing Type1CConverter with Ghostscript: gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dPDFSETTINGS=/printer -dColorConversionStrategy=/LeaveColorUnchanged -sOutputFile=pso.conv.tmp.pdf -f pso.conv.tmp.ps Type1CConverter: using interpreter GPL Ghostscript 854 20060517 Type1CConverter: converting font /JESDUO+MinionPro-It to /Obj0000000121 Type1CConverter: converting font /FJYGHI+MinionPro-ItSubh to /Obj0000000123 Type1CConverter: converting font /QPGEBD+MinionPro-MediumCapt to /Obj0000000125 Type1CConverter: converting font /VMUNVT+MinionPro-Regular to /Obj0000000127 Type1CConverter: converting font /KUASCT+MinionPro-Semibold to /Obj0000000129 Type1CConverter: converting font /PAMMIA+MnSymbol12 to /Obj0000000131 Type1CConverter: converting font /FJMZYA+CMSS12 to /Obj0000000133 Type1CConverter: converting font /HSDSIM+EUSM10 to /Obj0000000135 Type1CConverter: converting font /ZVUSPS+NimbusSanL-Regu to /Obj0000000137 Type1CConverter: all OK info: loading PDF from: pso.conv.tmp.pdf info: loaded PDF of 25351 bytes info: separated to 46 objs info: found 9 fonts in GS output info: optimized total Type1 font size 227324 to Type1C font size 13870 (6%) info: optimized Type1 font XObject 129,128: new size=2812 (7%) info: optimized Type1 font XObject 131,130: new size=1144 (5%) info: optimized Type1 font XObject 133,132: new size=640 (9%) info: optimized Type1 font XObject 135,134: new size=792 (31%) info: optimized Type1 font XObject 137,136: new size=2286 (39%) info: optimized Type1 font XObject 121,120: new size=1011 (2%) info: optimized Type1 font XObject 123,122: new size=1835 (4%) info: optimized Type1 font XObject 125,124: new size=913 (10%) info: optimized Type1 font XObject 127,126: new size=4994 (12%) info: eliminated 6 duplicate objs info: writing Multivalent input PDF: pso.conv.mi.tmp.pdf info: saving PDF with 134 objs to: pso.conv.mi.tmp.pdf info: generated 51111 bytes (19%) info: executing Multivalent to optimize PDF: java -cp /home/pts/prg/pdfsizeopt/trunk/Multivalent.jar tool.pdf.Compress pso.conv.mi.tmp.pdf file:/mnt/mandel/warez/tmp/pso.conv.mi.tmp.pdf, 51111 bytes PDF 1.4, producer=pdfTeX, creator=pdfTeX additional compression may be possible with: -compact => new length = 39032, saved 23%, elapsed time = 0 sec info: Multivalent generated pso.conv.mi.tmp-o.pdf of 39054 bytes (76%) info: compressed xref stream from 532 to 441 bytes (83%) info: optimized to 38949 bytes after Multivalent (100%) info: saving PDF to: Bishop-thesis.psom.pdf info: generated 38949 bytes (14%)
