I had a customer who contacted me to ask why every ‘t’ was duplicated in her report. I assumed that the customer was describing duplicate records and was ready to start troubleshooting the joins between tables. What I found, instead was that every letter ‘t’ in the text of the report was printing twice whenever the document was exported to PDF.  The Crystal preview was not affected.

So I did some web research and found that there is a rare glitch that can occur in some environments when using the Calibri font. It seems to be related to a DLL conflict but the simple solution for many users is to use a different font. If you run into this and a font change is not an option, you will have to try tracking down usp10.dll  to make sure Crystal is using the right version. These links might help:
