pdf--doc conversion problem

[lukija]

I have this pdf file downloaded and tried to convert it to doc so I could have a further use of it.Basically I'm in need of copying the content of this file whether it's pdf or doc for the translation purposes.Simply would like to copy and paste into translation tool to help me out with translation.The original text-saved in pdf format is written in Hebrew. I managed to turn pdf into doc but something must have gone wrong because it came up in form of symbols instead of usual print
Why?What shall I do?
BTW I used one of those free pdfs conversion programs...cannot remember its name but used by friend of mine.i'm a novice anyway
Plz help!
cheers

Ok not been precise enough due to lack of knowledge in this field.
The original document in pdf is a scan of hebrew book.A picture.So
what I did used one of those (pdf to doc ) programs to turn it into
doc hoping it would be readable.After that I opened doc using OCR
software named READ IRIS pro .But instead of hebrew symbols this
software brought up some very weird symbols not the usual prints.
So I wonder now what have I made wrong?
