Just noticed that the file size of my pdf was much bigger than yours so I checked my pdf export options (attached). When I choose "JPEG compression" or "Reduce Image Quality" I get formula errors in the pdf - although they do not look the same as yours, rather than Arabic characters I get a rectangle character appearing in numerous places.
Try replicating my settings and seeing if you still have the same problem. ** Attachment added: "Screenshot-PDF Options.png" http://launchpadlibrarian.net/36866801/Screenshot-PDF%20Options.png -- [ooo-build] OpenOffice exports PDF with arabic numerals instead of regular numbers https://bugs.launchpad.net/bugs/244353 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
