Hi,
A customer of mine asked me to change the font of some reports to Calibri. It all went well until we saved a report as PDF, there was way too much spacing between characters.
After some days of investigating and contact with Microsoft I’ve found out that it worked on a Windows Server 2008 R2 and the Calibri font files were almost double in size. So I replaced the font files with the ones from Windows Server 2008 R2 and the reports are working like a charm.
