# utf8 input encoding with biblatex (biber and bibencoding=utf8)

I have a document with Cyrillic, English and German. All worked well so far. But now I need a special Character in the bibliography.bib file. Its an \.{E}

If I just put that in there it gives me the following error:

! Package inputenc Error: Unicode char \u8:Ė not set up for use with LaTeX.

Here's a sample code that reproduces that behavior:

\documentclass[12pt,a4paper]{article}
\usepackage{amsmath,amsthm,amssymb,amsfonts}
\usepackage[T1,T2A]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage[english,russian,ngerman]{babel}

\usepackage[backend=biber,bibencoding=utf8]{biblatex}

\usepackage{filecontents}
\begin{filecontents}{onebook.bib}
@book{eichenbaum,
author={{\.{E}}jchenbaum},
title={Wie Gogol's \enquote{Mantel} gemacht ist},
}
\end{filecontents}
\nocite{*}

\begin{document}

\.{E}jchenbaum

Гоголь

Münze

\printbibliography

\end{document}


If I put a regular E in that .bib file, I get the following (and correct encoding as I want it outside the bibliography):

If I put that \.{E} in the .bib file and I comment out the line: % \usepackage[utf8]{inputenc} Then I get the following:

So the funny thing is, I can get the bibliography interact with my document file at the cost of losing encoding of regular text in there ...

As always, I appreciate any kind of help! Thanks!

• \usepackage{newunicodechar} and \newunicodechar{Ė}{\.{E}} should do. – egreg Apr 25 '14 at 15:17
• Ha! :insane laughter: So fast! So working! Thanks an awful lot! – fourreux Apr 25 '14 at 15:24
• With XeLaTeX and fontspec (and a font that contains all the glyphs such as Minion Pro) I have no problem to compile. – Bernard Apr 25 '14 at 15:43
• @ Bernard: I'll try that some day I have more time to look into it. Thanx. – fourreux Apr 25 '14 at 19:41

I wrote the newunicodechar just for solving similar problems, due to the fact that the Unicode support of inputenc is limited (but extendable).

You can do in two ways:

1. Look up in the Unicode table to find that Ė is U+0116 LATIN CAPITAL LETTER E WITH DOT ABOVE and add to your preamble

\DeclareUnicodeCharacter{0116}{\.{E}}

2. Copy the offending character from the terminal output or log file and paste it in the first argument of \newunicodechar:

\newunicodechar{Ė}{\.{E}}


Both ways should solve your problem.

• Is there a difference between the two of them? – fourreux Apr 25 '14 at 15:37
• @fourreux No, I just find the second way more readable. – egreg Apr 25 '14 at 15:43
