JabRef and Cyrillic citation

Question

It is a similar question to this one. However, I already defined my file.bib as UTF-8 and also similar to this question but my biggest problem is that I must follow ABNT and my university's format.

The file I have has an entry as such:

% This file was created with JabRef 2.10.
% Encoding: UTF8
@Article{russian2002,
  Title                    = {Эпидемиология опухолей головного мозга: статистические факторы},
  Author                   = {Розуменко, ВД},
  Journal                  = {Український нейрохірургічний журнал},
  Year                     = {2002},
  Number                   = {3},
  Pages                    = {47--48},
  Volume                   = {1},
Langid                   = {russian},
  Owner                    = {Rodrigo},
  Publisher                = {Національна академія медичних наук України, Інститут нейрохірургії ім. акад. АП Ромоданова, Українська Асоціація Нейрохірургів},
  Timestamp                = {2015.08.23}
}

Which is converted into this after running pdfLatex (through TexStudio):

\providecommand{\abntreprintinfo}[1]{%
 \citeonline{#1}}
\setlength{\labelsep}{0pt}\begin{thebibliography}{}
\providecommand{\abntrefinfo}[3]{}
\providecommand{\abntbstabout}[1]{}
\abntbstabout{1.52 }
\bibitem[Розуменко 2002]{russian2002}
\abntrefinfo{Розуменко}{Розуменко}{2002}
{Розуменко, . Эпидемиология опухолей
  головного мозга: статистические факторы.
\emph{Український нейрохірургічний журнал},
  Національна академія медичних наук
  України, Інститут нейрохірургії ім. акад.
  АП Ромоданова, Українська Асоціація
  Нейрохірургів, v.~1, n.~3, p. 47--48, 2002.}

And the compiler will give the same error as stated in this question

! LaTeX Error: Command \CYRF unavailable in encoding T1.

Unfortunately for me, there solution provided there does not work for me as when I try to use this:

\usepackage[backend=biber,language=auto,autolang=other]{biblatex}

It returns those two errors:

! LaTeX Error: Can be used only in preamble.

! Package biblatex Error: '\bibliographystyle' invalid.

Answer 1

Some juggles for keeping the ABNT class happy; the initials of the author's name must be treated specially because of how the bibliography style chops them.

Here I use filecontents just to keep the example self-contained.

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@Article{russian2002,
  Title     = {\textcyrillic{Эпидемиология опухолей головного мозга: статистические факторы}},
  Author    = {\SORTNOOP{Rozumenko}{\textcyrillic{Розуменко}}, {\VD}},
  Journal   = {\textcyrillic{Український нейрохірургічний журнал}},
  Year      = {2002},
  Number    = {3},
  Pages     = {47--48},
  Volume    = {1},
  Langid    = {russian},
  Owner     = {Rodrigo},
  Publisher = {\textcyrillic{Національна академія медичних наук України, 
               Інститут нейрохірургії ім. акад. АП Ромоданова, 
               Українська Асоціація Нейрохірургів}},
  Timestamp = {2015.08.23}
}
\end{filecontents*}
