BibTeX, biblatex and biber ⇒ Undefined control sequence on just one reference?

[arwintcher]

I am trying to compile my thesis document and I keep getting an "Undefined control sequence" error on a specific reference. I can't figure out what the problem is with it, though.

Here is my attempt at an MWE:

Code: Select all

\documentclass[a4paper,11pt,oneside]{memoir}
\usepackage[T1]{fontenc} %Encoding
\usepackage[latin1]{inputenc}
\chapterstyle{chappell}
\usepackage[authoryear,numbers,sort&compress]{natbib} 
\bibpunct[:]{(}{)}{;}{a}{}{,}
\begin{document}
\frontmatter
\mainmatter
\OnehalfSpacing
\pagestyle{companion}

Here is some random text that cites this file \cite[331]{sauvet09thinking}.

\bibliographystyle{plain}
\thispagestyle{empty}
\bibliography{sauvet}
\end{document}

The output in the bbl file, after running BibTeX:

Code: Select all

\begin{thebibliography}{1}

\bibitem{sauvet09thinking}
Georges Sauvet, Robert Layton, Tilman Lenssen-Erz, Paul Ta\ccon, and Andr\'e
  Wlodarczyk.
\newblock Thinking with animals in upper palaeolithic rock art.
\newblock {\em Cambridge Archaeological Journal}, 19(03):319--336, 2009.

\end{thebibliography}

The bibtex file is like this:

Code: Select all

@ARTICLE{sauvet09thinking,
  author = {Sauvet, Georges and Layton, Robert and Lenssen-Erz,Tilman and Ta\ccon,
	Paul and Wlodarczyk, Andr\'e},
  title = {Thinking with Animals in Upper Palaeolithic Rock Art},
  journal = {Cambridge Archaeological Journal},
  year = {2009},
  volume = {19},
  pages = {319-336},
  number = {03},
  doi = {10.1017/S0959774309000511},
  eprint = {http://journals.cambridge.org/article_S0959774309000511},
  file = {sauvet09thinking.pdf:sauvet09thinking.pdf:PDF},
}

I keep getting the error "Undefined control sequence ...rt Layton, Tilman Lenssen-Erz, Paul Ta\ccon", but I don't see what is wrong with the BibTeX entry. All the other hundreds of references in the file compile with no errors.

Sorry for not being thorough, but you should check two things:

1. \c in the name of Ta\ccon,

2. This line: \bibpunct[:]{(}{)}{;}{a}{}{,}

After removing \c and commenting that \bibpunct... line, bibliography compiled fine.

I do!

Change Ta\ccon to Ta{\c{c}}on.

While you're at it, change Andr\'e to Andr{\'e}.

BibTeX does not handle accents very well, but the first one would be incorrect even in plain LaTeX.

[arwintcher]

Ahhhhh. I wrote out the author names in Kile so that I could use the feature that automatically changes characters written with dead keys to latex code, using the shortcut key for ç (win+,+c) and \cc is what it spit out.

I changed it to \c{c} and it works now. Thanks!

I know just enough about latex to be dangerous...
