Rounak: I am aware that Adobe Export can convert a .pdf to Word file and also the website you suggested; however, the languages supported by Adobe Export do not include Russian (http://forums.adobe.com/docs/DOC-1812) - only English, German, Spanish, French, Italian and Japanese - that is what worries me.
Does Adobe Acrobat have OCR for Russian/Cryllic? Getting the .pdf to Word I understand now - my concern is the program's ability to read and export the Russian alphabet symbols, which look quite different from Arabic letters and can end up looking like gibberish in the Word export.
