# Multilingual bibliography using XeTeX, biblatex and polyglossia

I am trying to write text in Russian language with some citations in Russian, English and German references using XeLaTeX + polyglossia + biblatex + biber. As a biblatex style I use biblatex-gost which processes multilingual bibliographies fine with usual LaTeX + babel + bibtex, but the results in XeLaTeX are not so good - all fields are not localized.

My .tex file:

\documentclass[11pt, a4paper]{article}

\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text}
\usepackage{xunicode}
\usepackage{xltxtra}
\usepackage{csquotes}

\setmainfont{Palatino Linotype}
\setsansfont{Arial}
\setmonofont{Courier New}

\sloppy
\hyphenpenalty=10000

\usepackage{polyglossia}
\setdefaultlanguage{russian}
\setotherlanguages{english, german}

\usepackage[%
backend=biber,
bibstyle=gost-numeric,
language=auto,
babel=other,
sorting=ntvy,
doi=false,
eprint=false,
isbn=false,
dashed=false
]{biblatex}
\addbibresource{../bib/thesis.bib}

\begin{document}
Some text \cite{Gonzalez2002,Gonzalez2005ru}.

\printbibliography
\end{document}

thesis.bib file:

@BOOK{Gonzalez2002,
title = {Digital Image Processing},
publisher = {Prentice Hall},
year = {2002},
author = {R. C. Gonzalez and R. E. Woods},
pages = {793},
edition = {2},
language = {english},
hyphenation = {english}
}

@BOOK{Gonzalez2005ru,
title = {Цифровая обработка изображений : Пер. с англ},
publisher = {М.: Техносфера},
year = {2005},
author = {Р. Гонсалес and Р. Вудс},
pages = {1072},
language = {russian}
}

The result pdf looks like this:

but should:

I've read that biblatex cannot work with polyglossia (at least it was so some time ago), but I hope there is a possible solution and would be very grateful if anyone could help me.

UPD: As a TeX-system I use TeXLive 2012.

The babel=other setting only works with babel loaded. A solution would require adding a polyglossia interface to biblatex. If you can't work with babel and xecyr, consider submitting a feature request. – Audrey Jan 10 '13 at 21:01
I get \edef\gostmedialanguage{russian} when I try to compile Your document. – Adobe May 20 '13 at 15:16
We have just submitted a potential fix for polyglossia support to the 2.8 DEV biblatex version on SF. Please try it and report any problems to the enhancement request here: github.com/plk/biblatex/issues/69 – PLK Sep 28 '13 at 13:00
Yes, great, thanks! Now it works. – darkled Nov 7 '13 at 16:53

The authors should know better but as far as I know Biblatex does not officially support polyglossia (unfortunately). I use Babel with xecyr which seems to work fine, although I've not tested it thoroughly.

UPDATE: Polyglossia support has been added to Biblatex since ver.2.8.
