# BibLatex Chinese Characters in reference, XeLatex not an option

by Pia   Last Updated April 15, 2019 11:23 AM

I am need to cite chinese authors in my thesis. It works fine with Latex but not in BibLatex where I need to cite it within my refernces. Using Xelatex is not an option, as too many errors are showing when converting it. I tried several options before but none of them are working for Biblatex without Xelatex. Any new suggestions?

Edit:

I've been asked to post an example, an entry in my .bib file would look like this:

@misc{chin2012pat,
author={彤陈},
year={2012},
title={Obtaining fatty acids from insect larvae},
howpublished={Investigacion y Comercializacion
Biotecnologica Omebit S.A, Santiago. US8895767 B2},
note={Jun. 11, 2010},
}


As for what I've tried before: I tried to use a CJK block in biblatex, of course that didn't compile properly. I then tried to search stackexchange, unfortunately all solutions involve xelatex.

I don't have a lot of chinese references in my paper, so I was thinking there could be some way to "hardcode" it in, but I'm out of guesses.

Thanks a lot!

Calling biblatex with the option bibencoding=utf8 ensures that unknown Unicode points will be saved as \x{<code point>} in the .bbl file. With the help of \bibsetup we can then change the meaning of \x to do what we prefer with its argument.

For instance, I defined \x to be \chinesechar (a macro name of my own invention), that loads a graphic file named pia<code point>, that I prepared with XeLaTeX; for example, this is pia5f64.tex:

\documentclass{standalone}
\usepackage{fontspec}
\setmainfont{Songti SC}
\begin{document}
^^^^5f64
\end{document}


The other character is Unicode U+9648.

If you are able to coerce CJKutf8 into producing a character from its Unicode, then this indirect method is not necessary. Unfortunately, the documentation seems to be only in Chinese.

I also added a sortname field to the bib entry, in order to get correct alphabetic sorting (I hope Google Translate guessed right).

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@misc{chin2012pat,
author={彤陈},
sortname={{Chen Tong}},
year={2012},
title={Obtaining fatty acids from insect larvae},
howpublished={Investigacion y Comercializacion
Biotecnologica Omebit S.A, Santiago. US8895767 B2},
note={Jun. 11, 2010},
}
@article{a,
author={A. Uthor},
title={Title},
journal={Journal},
year=2013,
}
@article{b,
author={T. Best},
title={Title},
journal={Journal},
year=2013,
}
\end{filecontents*}

\documentclass{article}

\usepackage{graphicx}

\usepackage[bibencoding=utf8]{biblatex}
\appto\bibsetup{\let\x\chinesechar}

\newcommand\chinesechar[1]{\includegraphics[height=\fontcharht\fontT]{pia#1}}

\begin{document}

\cite{chin2012pat}, \cite{a}, \cite{b}

\printbibliography

\end{document}


## Maybe better method

I did some blind experiment with CJKutf8 and this seems to work.

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@misc{chin2012pat,
author={{\begin{CJK*}{UTF8}{gbsn}彤陈\end{CJK*}}},
sortname={{Chen Tong}},
year={2012},
title={Obtaining fatty acids from insect larvae},
howpublished={Investigacion y Comercializacion
Biotecnologica Omebit S.A, Santiago. US8895767 B2},
note={Jun. 11, 2010},
}
@article{a,
author={A. Uthor},
title={Title},
journal={Journal},
year=2013,
}
@article{b,
author={T. Best},
title={Title},
journal={Journal},
year=2013,
}
\end{filecontents*}

\documentclass{article}
\usepackage{CJKutf8}

\usepackage{graphicx}

\usepackage[bibencoding=utf8]{biblatex}

\begin{document}

\cite{chin2012pat}, \cite{a}, \cite{b}

\printbibliography

\end{document}


## Note

The filecontents* environment is just for convenience in preparing self-contained examples. You don't need it, just supply your own .bib file in the \addbibresource instruction.

Just for reference, looks like everything works OK now (2019) using plain bib entry author={彤陈}, in xelatex with fontspec and a suitable font, and biblatex/biber:

MWE:

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@misc{chin2012pat,
%  author={{\begin{CJK*}{UTF8}{gbsn}彤陈\end{CJK*}}},
author={彤陈},
sortname={{Chen Tong}},
year={2012},
title={Obtaining fatty acids from insect larvae},
howpublished={Investigacion y Comercializacion
Biotecnologica Omebit S.A, Santiago. US8895767 B2},
note={Jun. 11, 2010},
}
@article{a,
author={A. Uthor},
title={Title},
journal={Journal},
year=2013,
}
@article{b,
author={T. Best},
title={Title},
journal={Journal},
year=2013,
}
\end{filecontents*}
