I was not able with the help of Google to solve my problem yet. I have a reference from a Russian journal. That's why I entered the authors and journal title in cyrillic letters in JabRef. Now I run into problems when compiling the document with TeXStudio.
Does someone of you have experience with that?
My current encoding in JabRef is Cp1252 and after a lot of experimentation I stopped with the following packages:
\usepackage[russian,english]{textcomp}
\usepackage[utf8]{inputenc}
\usepackage[T1,T2A]{fontenc}
\usepackage[UKenglish,russian]{babel}
\usepackage[utf8]{inputenc} \usepackage[T2A,OT1]{fontenc}and then I can change my keyboard layout and type directly in Cyrillic. – Sigur Jan 03 '15 at 13:46
