You are using a type of font within a document and when you convert to a PDF there are large "." replacing "ti".
Resolution:
What seems to be happening is that the programmers application is using special character codes to represent ‘ti’. Certain combinations of characters such as ‘ti’, ‘fi’, ‘fl’, called ligatures, can be represented as a single Unicode character code rather than two characters. To convert these ligatures into PDF, multi-language support is required:

...and the following flags need to be set in FileNameOptionsEx:
MultilingualSupport + EmbedStandardFonts + EmbedLicensedFonts
If this does not work, please print to a Postscript file using any Postscript printer attached to file and send the .ps file to support@amyuni.com.
