I just tried to convert the electronic russian versions of the kvant magazine into english using google translate. As I found out not many(with not many i mean about 100-150) articles were available in pdf format. The problem I am facing with these pdf documents is that they are written in basically two fonts -the introductory para in a font recognisable by google translator as well as a few cyrillic fonts i have downloaded for ms word.However the remaining paragraphs are written in a font not recognisable by either of these systems. I want to know how can i determine in which font are these remaining paras are written so that i can download it and carry on the translation work. Just download one kvant problems page from here 😦http://kvant.mccme.ru/pdf/2001/04/kv0401probl.pdf).
