I use the xelatex with the biblatex package and with indexing author names. The biber works fine with bibliography of books in English and in Russian. The author index is generated. In the bibliography the order is correct but in the index of names I get bad order - Russian names does not follow the latin index names order. How can I correct it? Here is the test.tex example:


\documentclass{article}

\usepackage{geometry}
\geometry{a5paper}

\usepackage{xltxtra}
\usepackage{polyglossia}

\setdefaultlanguage{english}
\setotherlanguages{russian}
\defaultfontfeatures{Mapping=tex-text}
\setmainfont{FreeSerif}
\newfontfamily\russianfont{FreeSerif}

\usepackage{index}
\newindex{default}{idx}{ind}{My Index}
\newindex{titles}{tdx}{tnd}{My Titles}

\usepackage[style=authortitle-icomp,indexing=true,sorting=nty,backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\DeclareIndexFieldFormat{indextitle}{\index[titles]{#1}}

\listfiles
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@BOOK{Alma,
    author = {Alma, B.},
    title = {Test},
    year = {2000}
}
@INBOOK{Roma,
    author = {Рома, Ю.},
    title = {Oбраз},
    booktitle = {Материал},
    year = {2001},
    sortkey = {Roma}
}
@BOOK{Sama,
    author = {Sama, C.},
    title = {Last one},
    year = {2002}
}
\end{filecontents}

\begin{document}

\section{Testing}

Three \cite{Sama}.
Two \cite{Roma}.
One \cite{Alma}.

\printbibliography

\printindex

\end{document}

The References are almost OK (there are two dots after the Рома, Ю):

References
Alma, B. Test. 2000.
Рома, Ю.. “Oбраз”. In: Материал. 2001.
Sama, C. Last one. 2002.

But the index is not (by means of makeindex test):

My Index
Alma, B., 1
Sama, C., 1
Рома, Ю., 1

The texindy test.idx makes the same error:

A
Alma, B., 1
S
Sama, C., 1
Рома, Ю., 1

This is, of course, because in the test.idx we have 

\indexentry {Sama, C.}{1}
\indexentry {Рома, Ю.}{1}
\indexentry {Alma, B.}{1}
\indexentry {Alma, B.}{1}
\indexentry {Рома, Ю.}{1}
\indexentry {Sama, C.}{1}
We should have there something like: 
\indexentry {Roma@Рома, Ю.}{1}
because there is sortkey = {Roma} in the bib file for biblatex.

  • Hmm, I suspect the "bibencoding=inputenc" - biber will handle this as it converts to UTF-8 internally for sorting but for indexing, I suppose that depends on the indexing package you are using - like @egreg says, we need a MWE. – PLK Apr 30 '13 at 17:26

    Have a look at: http://tex.stackexchange.com/questions/22785 I suspect that you need to be using xindy for UTF-8 indexing - then you could drop the \textrussian – PLK Apr 30 '13 at 21:11
  • I think in the end this comes down to the linked problem: you need to index using Xindy. – Joseph Wright Dec 17 '14 at 07:26
