Yes, Idolse, it was my mistake considering that rtf should do it. I did what you suggested and now the display is correct.
Thank you all for your help.
On another note, since I have lots of pdf's with specific Romanian characters, I tried to find a program to convert to doc or whatever with not much success until recently. I am using now "ABBYY Fine Reader Express" that is using OCR (Optical character recognition) technology and it works just fine. This is a success case if someone is using a Mac.
