Mangled output of accented characters with biblatex-chicago and babel (Brazilian localization, not input)

Question

I'm having trouble with biblatex-chicago's localized output. Here's the MWE:

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\usepackage{csquotes}
\usepackage[brazil]{babel}
\usepackage[authordate,backend=biber,bibencoding=inputenc]{biblatex-chicago}
\usepackage{filecontents}

\begin{filecontents}{bibliography.bib}
@book{aristoteles1997,
  author =  {Aristóteles},
  title =  {Ação},
  editor =  {John Doe},
  editora = {Jane Doe},
  editoratype = {collaborator},
  publisher =  {Pub Inc},
  year =  1997,
}
\end{filecontents}

\addbibresource{bibliography.bib}
\begin{document}
\cite{aristoteles1997}
\printbibliography
\end{document}

I process this file with:

pdflatex mwe
biber mwe
pdflatex mwe
pdflatex mwe

The resulting bibliography is as follows:

As you can see, "Referências", "Aristóteles" and "Ação" are all correctly rendered, and the whole thing is localized, as expected, to Brazilian Portuguese.

But the "Em colaboração com" part ("In collaboration with") is mangled.

Does anyone know what is going on and how I can fix this?

Answer 1

You can declare your own localizations strings (fixes missing ç):

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\usepackage{csquotes}
\usepackage[brazil]{babel}
\usepackage[authordate,backend=biber,bibencoding=inputenc]{biblatex-chicago}
\usepackage{filecontents}

\DefineBibliographyStrings{brazil}{bycollaborator={Em colaboração com}}

\begin{filecontents}{bibliography.bib}
@book{aristoteles1997,
  author =  {Aristóteles},
  title =  {Ação},
  editor =  {John Doe},
  editora = {Jane Doe},
  editoratype = {collaborator},
  publisher =  {Pub Inc},
  year =  1997,
}
\end{filecontents}

\addbibresource{bibliography.bib}
\begin{document}
\cite{aristoteles1997}
\printbibliography
\end{document}
