Converting the attached PDF file to PS via -sDEVICE=pdfwrite results in a PS file that is missing most (but not all) of the lowercase characters. Both Ghostscript and Apple Preview open the resulting PS file in the same way, so I believe the error to be in the pdfwrite device

Created attachment 2617 [details] 689001.ps In the initial description of the bug please replace "PDF file to PS" with "PS file to PDF" and "resulting PS file" with "resulting PDF file".
I found this to caused by Type 0 fonts with Type 3 descendents, a cause common to all the following: Bug #688639 "pdfwrite: a composite font with a Type 3 descendent and FMapType 2" Bug #688760 "ps2pdf loses text in postscript figure when converted to pdf" Bug #688954 "Text disappears when converting some ps files with ps2pdf" Bug #689001 "Characters lost converting PS to PDF" Bug #689041 "Japanese Font Display Problem is ps2pdf" Bug #689105 "Invalid fonts error during converting from PS to PDF" For a fix, please see bug #688639 comment #13. I suggest to close this bug as a duplicate of bug #688639.
