Bug kryptic characters

[MoonKId]

I am using FoxitReader under Kubuntu 12.04. In a document there are not all characters displayed correctly. Pleas see the screenshot with the words "specific", "identification", "classification".

The same document is well displayed wit Ocula (on the same system) and with AdobeReader (on Android).



What is the problem behind that display bug? How can I fix it?

Thanks for the help.

We only tested under the Ubuntu8.10 envrionment, and unfortunately, due to human resources, we have stopped maintaining Reader for Linux. But we are developing windows-less frame Reader that can run across platforms. That will be a substitute version of current one.
