CRYSTAL REPORT EXPORT TO PDF INSERTS lowercasee i after t

I have a crystal report file that is stored as image type in table (SQL Server).When i open the report file in my application (Visual Studio (C#) ), it shows the required one.But When i export to pdf and save it to my local hard drive, and if i open that file, i find that after every lowercase 't' , letter 'i' is appended.I searched through google and found that it migh be a font issue.Even after changing the font, i was not able to resolve the issue.

Example : 'Project' becomes 'Projecti'

Please provide a resolution to this issue
