PdfHandler passes the PDF file off to GhostScript to render pages to JPEGs... if the fonts are embedded, it shouldn't have a problem unless there's a bug in GS.
Could be a production-level problem (bad version or config of GS).

Hopefully we'll be upgraded to lucid before too long...

gs rendering output of sample file first page on Ubuntu 10.04 Lucid
Here's rendering from my server that's running on Lucid.
Command line:
gs -sDEVICE=jpeg -sOutputFile=- -dFirstPage=1 -dLastPage=1 -r150 -dBATCH -dNOPAUSE -q WM_CZ_2010_Annual_Report_-_Czech.pdf > out.jpg
Appears pretty much identical to the bad output in production.

Which seems to suggest it's probably either a configuration issue, else an upstream bug...
The file rendered correctly for me locally using Ghostscript 9.15:
…therefore marking as depending on T110849: Upgrade Ghostscript to 9.15 or later.
https://meta.wikimedia.org/w/index.php?title=File%3AWM_CZ_2010_Annual_Report_-_Czech.pdf&page=1 and https://upload.wikimedia.org/wikipedia/meta/thumb/0/0a/WM_CZ_2010_Annual_Report_-_Czech.pdf/page1-424px-WM_CZ_2010_Annual_Report_-_Czech.pdf.jpg look exactly like https://phabricator.wikimedia.org/T31937#1588079 nowadays.
Hence assuming this problem has been fixed in the meantime by some other GhostScript update...
Please reopen if I misunderstood something.
