How to make appendix and hyperref packages work together with cyrillic (non ASCII) characters?

Question

I have a LaTeX document with hyperref and appendix packages that fails to build. But if I switch off either appendix or hyperref everything works fine.

\documentclass[14pt]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english,russian]{babel}
\usepackage[toc,page,title,titletoc]{appendix}
\usepackage{hyperref}
\begin{document}

\hypersetup{pdftex, colorlinks=true, linkcolor=blue, citecolor=blue, filecolor=blue, urlcolor=blue, pdftitle=, pdfauthor=, pdfsubject=, pdfkeywords=}

\renewcommand{\appendixtocname}{Приложения}
\renewcommand{\appendixpagename}{Приложения}
\renewcommand{\appendixname}{Приложениe}

\tableofcontents
\pagebreak
\section{тест}

\begin{appendices}


\renewcommand{\thesection}{\arabic{section}.}

\section{Тест}
\pagebreak
\section{Схема устройства}


\end{appendices}

\end{document}

Generated error:

<argument> \T 
          2A\CYRP \T 2A\cyrr \T 2A\cyri \T 2A\cyrl \T 2A\cyro \T 2A\cyrz...

Is there any possibility to use them together?

Quite hard problem. The guilty party is appendix that does some definitions that become incompatible with the way Russian is managed by Babel.

\documentclass[12pt]{article}

\usepackage[T2A,T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english,russian]{babel}
\usepackage[toc,page,title,titletoc]{appendix}
\usepackage{hyperref,bookmark}
\hypersetup{
  colorlinks=true,
  linkcolor=blue,
  citecolor=blue,
  filecolor=blue,
  urlcolor=blue,
  % pdftitle=,
  % pdfauthor=,
  % pdfsubject=,
  % pdfkeywords=
}

\renewcommand{\appendixtocname}{Приложения}
\renewcommand{\appendixpagename}{Приложения}
\renewcommand{\appendixname}{Приложние}
\makeatletter
\let\oriAlph\Alph
\let\orialph\alph
\renewcommand{\@resets@pp}{\par
  \@ppsavesec
  \stepcounter{@pps}
  \setcounter{section}{0}%
  \if@chapter@pp
    \setcounter{chapter}{0}%
    \renewcommand\@chapapp{\appendixname}%
    \renewcommand\thechapter{\@Alph\c@chapter}%
  \else
    \setcounter{subsection}{0}%
    \renewcommand\thesection{\@Alph\c@section}%
  \fi
  \if@pphyper
    \if@chapter@pp
      \renewcommand{\theHchapter}{\theH@pps.\oriAlph{chapter}}%
    \else
      \renewcommand{\theHsection}{\theH@pps.\oriAlph{section}}%
    \fi
    \def\Hy@chapapp{appendix}%
  \fi
  \restoreapp
}
\makeatother

\begin{document}


\tableofcontents
\pagebreak
\section{тест}

\begin{appendices}


\renewcommand{\thesection}{\arabic{section}.}

\section{Тест}
\pagebreak
\section{Схема устройства}


\end{appendices}

\end{document}

Note that it's better to load fontenc before inputenc.
