Question Displaying east european characters properly in pdf text

Hey guys,

I have a couple of pfd books in an eastern european (Czech) language and when I open them in acrobat or any other reader, they tend to miss some special characters such as "" and "". I am running CM10.1 with english (UK) locale. Is there any way to make the special characters display properly?
