When converting Eastern European alphabet written article from .nb to pdf, certain letters convert to empty rectangle like shapes or constructs, also hacek like letters (č,ć,ž,š,""...). Has anybody suggestion how to correct this?
I cannot reproduce this problem on OS X with the current version of Mathematica (9.0.1).
However, I think I remember a similar problem existing in some earlier versions of Mathematica, at least on Windows. If my memory is correct, a possible solution was to use one of the PDF printers (Acrobat Distiller, redmon, etc.) to print the notebook to PDF instead of using Save As ... PDF.
But then it is possible that I remember wrong.
