# One \cite crash all

I'm new to this. And I understand nothing. Please, explain me what happen. I use

    \usepackage[utf8]{inputenc}
\usepackage[
backend=biber,
style=authoryear,
natbib=true,
sorting=nyvt]{biblatex}


And I use

    \begin{document}
My text \citep{cite1} bla-bla-bla \citep{cite2}.
\newpage{}
\printbibliography[title={References}]
\end{document}


And all is good. Then I add

    bla-bla-bla \citep{troublecite}.


And I have "biber DocName: Command for 'biber DocName' gave return code 256" and "Entity: line 298: parser error : Extra content at the end of the document troublecite" Then I delete *.aux, *.bbl etc and I delete \citep{troublecite} - and all is fine again.

I try to delete this string out from my *.bib and add info by hands, I try to import citation file - but no positive result. And I don't know what to do. I have no ideas. Can anybody help me?

UPD

• Welcome to TeX.SE. Please show us the troublecite entry. – Mico Mar 10 '16 at 5:33
• Please also show the contents of the .blg file (Biber's log file). As Mico commented it would be great to see a full example including the .bib entry. This is best done in an MWE that we can just copy and run on our machines, please read help on MWEs and help on MWEBs. – moewe Mar 10 '16 at 6:46

Short answer: A hyphen in one of the bibliography entries gives an encoding error. To solve this, delete the letter and retype it.

How to find the one \cite to crash them all!!!

1. Make a copy or another form of backup of your project.

2. Find out which bibliography entry causes the problem by step by step removing the other ones or the cites in your .tex file [I find it easier to see if the error is gone, if I delete all the .log files between compilations, because otherwise it can survive there for a few compilations]

3. Find out which field is causing the error. Since Biblatex thankfully is very tolerant about missing fields, just remove field by field until the error is gone.

4. On could probably just have looked up the unicode number of the error message, but from experience - are prone to be some bad characters, so it was just a lucky guess. Other examples of characters prone to be in disguise are spaces, ligatures (such as ﬁ), accented letters or math symbols.

• Thank you very much. And very good point about removing the temporary files when trying to isolate the source of the problem. Depending on what is going on the error might still reside in one of the auxiliary files even if it is already fixed in the actual input. – moewe Mar 17 '16 at 12:25

TL;DR: Try to search and replace the '–' symbol by '-' in the pages field of your reference list.

Long version: I had a similar problem: The latex document could not be compiled anymore after adding a certain reference. I used Texmaker with pdflatex+biblatex. My problem was that the document simply never finished compiling.

To isolate the faulty entry, I needed to successively remove parts of the citations until it was working again (I recommend to do it via a Binary search). When compiling again, I needed to remove all auxiliary files (otherwise it would have crashed again). Please also note that the problem was only triggered when \printbibligraphy was in place and not when only in-text citations, e.g. via \cite{..} were used.

The dubious entry had a wrong '-' sign in the page numbers. The symbol was en dash and not the ordinary hyphen-minus. This caused latex to crash.

Interestingly, the en-dash symbol did not lead to a crash in other fields (e.g. in the title field).

• Welcome to TeX.SX! The dash is the typographically right device for page numbers, although in bib files you could use --. Other than that how does this differ from the existing answer? – TeXnician Aug 29 at 9:02
• Biber should not have a problem with an en-dash in a pages field (because Biber digests the en-dash there; in other fields an en-dash can be problematic since it is passed on to LaTeX, who may have trouble with it). That means that for the particular situation described in the question this answer does not really apply. – moewe Aug 29 at 9:15
