First off - Thank you for your help.
I have a strange issue with Adobe Reader where the font is not correctly displayed correctly as compared to the original document. Document diplays in a strange font as per attachment.
I have removed and re-installed Adobe reader. Updated Reader to a newer version. Installed Adobe pro (licenced) and as a last resort - removed and updated local display drivers.
Issue remains as per attached image.
Is this due to embedded fonts? How do i fix this? Re-imaging the machine is no go at this point.
Look at file > document properties > fonts and see if any are listed without the word "embedded" or "embedded subset" against them.
If a font isn't embedded and isn't available on your system, Adobe Reader will try and substitute another one - but it often looks strange. Aside from that without seeing the actual file we can't help, and of course Adobe Reader can't fix missing fonts; you have to either recreate the original PDF, or install the fonts on your computer.
I also think it is missing font. I download form internet a package of fonts and installed it and it works fine now.
